The Pratt & Whitney F100 (company designation JTF22 ) is a low bypass afterburning turbofan engine. It was designed and manufactured by Pratt & Whitney to power the U.S. Air Force's "FX" initiative in 1965, which became the F-15 Eagle . The engine was to be developed in tandem with the F401 which shares a similar core but with an upscaled fan for the U.S. Navy's F-14 Tomcat . The F401 was later abandoned due to costs and reliability issues. The F100 also powered the F-16 Fighting Falcon for the Air Force's Lightweight Fighter (LWF) program.

The U.S. Navy saw substantial action in the War of 1812 , where it was victorious in eleven single-ship duels with the Royal Navy. It proved victorious in the Battle of Lake Erie and prevented the region from becoming a threat to American operations in the area. The result was a major victory for

5074-413: The Chief of Naval Operations, Admiral Elmo Zumwalt , authorized the Navy to celebrate its birthday on 13 October to honor the establishment of the Continental Navy in 1775. The United States was without a navy for nearly a decade, a state of affairs that exposed U.S. maritime merchant ships to a series of attacks by the Barbary pirates . The sole armed maritime presence between 1790 and the launching of

5192-503: The Coast Guard may be called upon to operate as a service within the Navy. At other times, Coast Guard Port Security Units are sent overseas to guard the security of ports and other assets. The Coast Guard also jointly staffs the Navy's naval coastal warfare groups and squadrons (the latter of which were known as harbor defense commands until late-2004), which oversee defense efforts in foreign littoral combat and inshore areas. The United States Navy has over 400,000 personnel, approximately

5310-440: The F-14, such as the Super Tomcat 21 (ST-21), were to be powered by the F110-GE-429, the naval variant of the F110-GE-129 IPE. The F-16 Fighting Falcon entered service powered by the Pratt & Whitney F100 afterburning turbofan . Seeking a way to drive unit costs down, the USAF implemented the Alternate Fighter Engine (AFE) program in 1984, under which the engine contract would be awarded through competition. As of June 2005,

5428-599: The F-15 with its desired thrust-to-weight ratio of greater than 1:1 at combat weight. The F100-PW-100 first flew in an F-15 Eagle in 1972 with a maximum continuous power rating of 12,410 lbf (55.2 kN), military power of 14,690 lbf (65.3 kN), and afterburning thrust of 23,930 lbf (106.4 kN) with 5-minute limit. Due to the advanced nature of engine stemming from ambitious performance goals, numerous problems were encountered in its early days of service including high wear, stalling and "hard" afterburner starts. These "hard" starts could be caused by failure of

5546-679: The F-16's Modular Common Inlet Duct (MCID), or "Big Mouth" inlet introduced in the Block 30 variant. The -132 incorporates an improved fan that is more efficient and can increase maximum airflow, composite fan duct, durability improvements to the hot section, radial augmentor, and control system improvements. The engine leveraged research performed under the Integrated High Performance Turbine Engine Technology (IHPTET) program. The -132 produces 19,000 lbf (84.5 kN) of thrust in intermediate power and 32,500 lbf (144.6 kN) in afterburner but can also be tuned to run at -129 thrust levels to increase inspection intervals from 4,300 cycles to 6,000;

5664-449: The F100 on the F-15 and F-16), the DoD began procuring the upgraded TF30-P-414As. While these engines solved the serviceability problems, the fuel consumption and thrust was comparable to the initial model—considerably less than what the F-14 had been designed for; the F-14's originally planned Pratt & Whitney F401 , an upscaled naval development of the F100 design, was also canceled due to costs and reliability issues. After reviewing

5782-410: The F101 DFE was first fitted on an F-16 for flight testing, where it showed considerable improvement in performance and operability over the existing F100. In 1982, the Air Force began the full-scale development of the F101 DFE as an option to compete with the F100 for application in future F-15 and F-16 production; the engine was eventually selected for the F-16 and designated F110-GE-100 . The threat by

5900-557: The F110 has been cited as a reason for Pratt & Whitney to more quickly rectify the issues affecting the F100 and developing the improved F100-PW-220 variant. Seeking to drive unit costs down and improve contractor performance, the Air Force implemented the Alternate Fighter Engine (AFE) competition between the F100 and F110 in 1983 in what was nicknamed "The Great Engine War", where the engine contract would be awarded through competition. The Air Force would buy both engines starting in 1984, with contracts being competed every fiscal year and

6018-407: The F110 powered 86% of the USAF's F-16C/Ds. While the F110-GE-100 can provide around 4,000 lbf (17.8 kN) more thrust than the F100-PW-200, it requires more airflow for the jet to fully exploit the engine; the standard normal shock inlet (NSI) limited the F110 to 25,735 lbf (114.5 kN). This led to the increase in the area of the engine inlet for the MCID. The F-16C/D Block 30/32s were

7552-445: The United States Navy grew under an ambitious ship building program associated with the Naval Act of 1916 . Naval construction, especially of battleships, was limited by the Washington Naval Conference of 1921–22, the first arms control conference in history. The aircraft carriers USS  Saratoga  (CV-3) and USS  Lexington  (CV-2) were built on the hulls of partially built battle cruisers that had been canceled by

7670-518: The United States Navy. Most naval aviation insignia are also permitted for wear on uniforms of the United States Marine Corps . As described in Chapter 5 of U.S. Navy Uniform Regulations, "badges" are categorized as breast insignia (usually worn immediately above and below ribbons) and identification badges (usually worn at breast pocket level). Breast insignia are further divided between command and warfare and other qualification . General Electric F110#Design The General Electric F110

7788-431: The ambitious raw performance goals for the F100 of high thrust and low weight, the F110 placed a greater emphasis on balancing between reliability, operability, and performance. The fan and inlet guide vanes were designed to smooth airflow to increase resistance to compressor stalls. The engine has an electronic and hydromechanical control system that make it more forgiving of rapid throttle inputs. The main difference between

7906-508: The burden of retaliating against the Japanese on the small number of aircraft carriers. During World War II some 4,000,000 Americans served in the United States Navy. The potential for armed conflict with the Soviet Union during the Cold War pushed the U.S. Navy to continue its technological advancement by developing new weapons systems, ships, and aircraft. U.S. naval strategy changed to that of forward deployment in support of U.S. allies with an emphasis on carrier battle groups. The navy

8024-419: The capture of California with large-scale land operations coordinated with the local militia organized in the California Battalion . The Navy conducted the U.S. military's first large-scale amphibious joint operation by successfully landing 12,000 army troops with their equipment in one day at Veracruz , Mexico. When larger guns were needed to bombard Veracruz, Navy volunteers landed large guns and manned them in

8142-411: The current U.S. Navy remains an asset for the United States. Moreover, it is the principal means through which the U.S. maintains international global order, namely by safeguarding global trade and protecting allied nations. In 2007, the U.S. Navy joined with the U.S. Marine Corps and U.S. Coast Guard to adopt a new maritime strategy called A Cooperative Strategy for 21st Century Seapower that raises

8260-405: The designation -129C. Further improved subvariants with 6,000-cycle intervals were designated -129D (for the F-16) and -129E (for the F-15). The -129E also powers the TAI Kaan prototype. The F-14A entered service with the United States Navy in 1973 powered by Pratt & Whitney TF30s . By the end of the decade, following numerous problems with the original engine (and similar problems with

8378-464: The end of the war. The U.S. Navy had followed in the footsteps of the navies of Great Britain and Germany which favored concentrated groups of battleships as their main offensive naval weapons. The development of the aircraft carrier and its devastating use by the Japanese against the U.S. at Pearl Harbor, however, shifted U.S. thinking. The Pearl Harbor attack destroyed or took out of action a significant number of U.S. Navy battleships. This placed much of

8496-492: The engine was canceled due to costs and development issues. The PW1120 turbofan was a smaller derivative of the F100; it was installed as a modification to a single F-4E fighter jet, and powered the canceled IAI Lavi . Related development Comparable engines Related lists United States Navy 13 October 1775 (249 years, 1 month) (as the Continental Navy ) The United States Navy ( USN )

8614-475: The excess thrust available. Early problems were eventually solved by the development of the F100-PW-220 in the early 1980s, which the -100 could be upgraded to. The F-16 Fighting Falcon entered service with the F100-PW-200; compared to the -100, the -200 has some additional redundancies for single-engine reliability and almost identical thrust ratings. In particular, a "proximate splitter" was introduced on

8732-526: The face of the expiration of budget relief offered by the Bipartisan Budget Act of 2013 and CNO Jonathan Greenert said that a ten ship carrier fleet would not be able to sustainably support military requirements. The British First Sea Lord George Zambellas said that the USN had switched from "outcome-led to resource-led" planning. One significant change in U.S. policymaking that is having

8850-569: The fighter engine market. The engine attracted the interest of the Air Force's Engine Model Derivative Program (EMDP), and in 1979 began funding it as the F101 Derivative Fighter Engine, or F101 DFE. The Air Force saw the F101 DFE as a potential alternative to the F100 and also a way to coerce better performance from Pratt & Whitney in addressing issues with the F100. Following the completion of ground tests in 1980,

8968-654: The first three commands being led by four-star admirals. The United States First Fleet existed after World War II from 1947, but it was redesignated the Third Fleet in early 1973. The Second Fleet was deactivated in September 2011 but reestablished in August 2018 amid heightened tensions with Russia. It is headquartered in Norfolk, Virginia, with responsibility over the East Coast and North Atlantic. In early 2008,

9086-566: The first three were brought into service: USS  United States , USS  Constellation , and USS  Constitution . Due to his strong posture on having a strong standing Navy during this period, John Adams is "often called the father of the American Navy". In 1798–99 the Navy was involved in an undeclared Quasi-War with France. From 1801 to 1805, in the First Barbary War , the U.S. Navy defended U.S. ships from

9204-424: The first time at the Battle of Hampton Roads in 1862, which pitted USS  Monitor against CSS  Virginia . For two decades after the war, however, the U.S. Navy's fleet was neglected and became technologically obsolete . A modernization program beginning in the 1880s when the first steel-hulled warships stimulated the American steel industry, and "the new steel navy" was born. This rapid expansion of

9322-445: The first to be built with a common engine bay, able to accept both engines, with Block 30s having the bigger MCID inlet (also known as "Big Mouth") for the F110 and Block 32s retaining the standard inlet for the F100. The F-16C/D Block 30 and 40 were powered by the 28,200 lbf (125.4 kN) F110-GE-100, while the Block 50 was powered by the 29,500 lbf (131.2 kN) F110-GE-129 IPE. The United Arab Emirates ' F-16E/F Block 60

9440-491: The first uniform regulations for officers were issued in 1802 on the formation of the Navy Department. The predominant colors of U.S. Navy uniforms are navy blue and white. U.S. Navy uniforms were based on Royal Navy uniforms of the time and have tended to follow that template. Navy officers serve either as a line officer or as a staff corps officer . Line officers wear an embroidered gold star above their rank of

9558-456: The fleet has shrunk and that in the face of declining budgets in the future, the U.S. Navy must rely even more on international partnerships. In its 2013 budget request, the navy focused on retaining all eleven big deck carriers, at the expense of cutting numbers of smaller ships and delaying the SSBN replacement. By the next year the USN found itself unable to maintain eleven aircraft carriers in

9676-705: The fleet, and making naval technological improvements. During the Mexican–American War the U.S. Navy blockaded Mexican ports, capturing or burning the Mexican fleet in the Gulf of California and capturing all major cities in Baja California peninsula. In 1846–1848 the Navy successfully used the Pacific Squadron under Commodore Robert F. Stockton and its marines and blue-jackets to facilitate

9794-698: The hands of the Barbary pirates from Algiers , the United States Congress passed the Naval Act of 1794 for the construction of six heavy frigates , the first ships of the Navy. The United States Navy played a major role in the American Civil War by blockading the Confederacy and seizing control of its rivers. It played the central role in the World War II defeat of Imperial Japan . The United States Navy emerged from World War II as

9912-798: The late 1990s. Both the -232 and its competitor, the General Electric F110-GE-132, were designed to make full use of the F-16's Modular Common Inlet Duct (MCID), or "Big Mouth" inlet introduced in the Block 30 variant. The fan module was redesigned for increased airflow of 275 lb/s (125 kg/s) and greater reliability; it incorporated stages with wide chord blades and disk formed into a single piece called an integrally-blades rotor (IBR), or blisk . The stators were also redesigned for better aerodynamics to improve stall margin. The -232 could produce 20,100 lbf (89.4 kN) of thrust in intermediate power and 32,500 lbf (144.6 kN) in afterburner; alternatively it could produce

10030-639: The latter's failure due to costs and reliability issues, and chose to continue to use the Pratt & Whitney TF30 engine from the F-111 in its F-14s. The F100 is a twin spool, axial flow, afterburning turbofan engine. It has a 3-stage fan driven by a two-stage low-pressure turbine and a 10-stage compressor driven by a two-stage high-pressure turbine. The initial F100-PW-100 variant generates nearly 24,000 lbf (107 kN) of thrust in full afterburner and weighs approximately 3,000 lb (1,361 kg), achieving its target thrust-to-weight ratio of 8 and providing

10148-422: The mid-1980s, the Air Force sought greater power for its tactical fighters and began Improved Performance Engine (IPE) programs for the F100 and F110, with the goal of achieving thrust in the 29,000 lbf (129 kN) class, while retaining the durability improvements achieved in the F100-PW-220 and F110-GE-100. The result would be the Pratt & Whitney F100-PW-229 and General Electric F110-GE-129 . Compared to

10266-468: The mission of the U.S. Armed Forces is "to be prepared to conduct prompt and sustained combat operations in support of the national interest." The Navy's five enduring functions are: sea control , power projection , deterrence , maritime security , and sealift . It follows then as certain as that night succeeds the day, that without a decisive naval force we can do nothing definitive, and with it, everything honorable and glorious. Would to Heaven we had

10384-529: The most common ground since aircrews are guided in their use of aircraft by standard procedures outlined in a series of publications known as NATOPS manuals. The United States Coast Guard , in its peacetime role with the Department of Homeland Security , fulfills its law enforcement and rescue role in the maritime environment. It provides Law Enforcement Detachments (LEDETs) to Navy vessels, where they perform arrests and other law enforcement duties during naval boarding and interdiction missions. In times of war,

10502-476: The most important is the "warfare qualification", which denotes a journeyman level of capability in Surface Warfare, Aviation Warfare, Information Dominance Warfare, Naval Aircrew, Special Warfare, Seabee Warfare, Submarine Warfare or Expeditionary Warfare. Many qualifications are denoted on a sailor's uniform with U.S. Navy badges and insignia . The uniforms of the U.S. Navy have evolved gradually since

10620-597: The most powerful navy in the world. The modern United States Navy maintains a sizable global presence, deploying in strength in such areas as the Western Pacific , the Mediterranean , and the Indian Ocean. It is a blue-water navy with the ability to project force onto the littoral regions of the world, engage in forward deployments during peacetime and rapidly respond to regional crises, making it

10738-495: The naval service dress uniform while staff corps officers and commissioned warrant officers wear unique designator insignias that denotes their occupational specialty. Warrant and chief warrant officer ranks are held by technical specialists who direct specific activities essential to the proper operation of the ship, which also require commissioned officer authority. Navy warrant officers serve in 30 specialties covering five categories. Warrant officers should not be confused with

10856-779: The notion of prevention of war to the same philosophical level as the conduct of war. The strategy was presented by the Chief of Naval Operations , the Commandant of the Marine Corps , and Commandant of the Coast Guard at the International Sea Power Symposium in Newport, Rhode Island on 17 October 2007. The strategy recognized the economic links of the global system and how any disruption due to regional crises (man-made or natural) can adversely impact

10974-465: The number two official in the Navy Department during World War I, appreciated the Navy and gave it strong support. In return, senior leaders were eager for innovation and experimented with new technologies, such as magnetic torpedoes, and developed a strategy called War Plan Orange for victory in the Pacific in a hypothetical war with Japan that would eventually become reality. The U.S. Navy grew into

11092-539: The ocean-going schooner USS Hannah to interdict British merchantmen and reported the captures to the Congress. On 13 October 1775, the Continental Congress authorized the purchase of two vessels to be armed for a cruise against British merchantmen; this resolution created the Continental Navy and is considered the first establishment of the U.S. Navy. The Continental Navy achieved mixed results; it

11210-678: The older -129 can be upgraded to the -132 configuration, with the new fan being a modular component. The F110-132 was selected to power the F-16E/F Block 60 for the United Arab Emirates . Engine flight tests began in 2003, and first delivery was in 2005. Technology from the -132 as well as from commercial CFM56 developments are shared with the F110 Service Life Extension Program (SLEP), and F110-129 upgraded with SLEP technology were given

11328-427: The operational environment, as an expeditionary force specializing in amphibious operations, Marines often embark on Navy ships to conduct operations from beyond territorial waters. Marine units deploying as part of a Marine Air-Ground Task Force (MAGTF) operate under the command of the existing Marine chain of command. Although Marine units routinely operate from amphibious assault ships, the relationship has evolved over

11446-451: The other organizations, playing a coordinating role. In 1834, the United States Marine Corps came under the Department of the Navy. Historically, the Navy has had a unique relationship with the USMC, partly because they both specialize in seaborne operations. Together the Navy and Marine Corps form the Department of the Navy and report to the Secretary of the Navy. However, the Marine Corps

11564-456: The percentages of F100 versus F110 would vary based on contract; the competitions eventually ended in 1992. The F101 DFE was also tested in the F-14B prototype in 1981, and the aircraft saw considerable performance improvement over the existing Pratt & Whitney TF30 . Although further testing was halted by the Navy in 1982, it would use the results of the Air Force's AFE evaluation to choose

11682-401: The powerplant for future F-14s. The F101 DFE was eventually chosen by the Navy in 1984 and was designated F110-GE-400 . The F110-GE-100/400 is a low-bypass axial-flow afterburning turbofan. It has a 3-stage fan driven by a two-stage low-pressure turbine and a 9-stage compressor driven by a one-stage high-pressure turbine; overall pressure ratio is 30.4 and bypass ratio is 0.87. In contrast to

11800-513: The results of the Air Force's AFE evaluation, the Navy would choose the F101 DFE to re-engine the F-14 in 1984, with the variant designated the F110-GE-400; the primary difference between the -400 and the Air Force's F110-GE-100 is length — the -400 had a 50-inch (1.3 m) tailpipe extension to suit the F-14 airframe, which was fitted downstream of the augmentor. During initial years of service,

11918-495: The same thrust levels as the -229 but increase inspection intervals by 40%. The -232 was not pursued by the USAF, but many of the improvements were incorporated into the -229EEP to increase its reliability and inspection intervals. Data from Pratt & Whitney, Flight International The F401 was the naval development of the F100 and designed in tandem. It was intended to power the F-14B Tomcat and Rockwell XFV-12 , but

12036-718: The senior command meant that naval forces were not contributed until late 1917. Battleship Division Nine was dispatched to Britain and served as the Sixth Battle Squadron of the British Grand Fleet. Its presence allowed the British to decommission some older ships and reuse the crews on smaller vessels. Destroyers and U.S. Naval Air Force units like the Northern Bombing Group contributed to the anti-submarine operations. The strength of

12154-1052: The shore establishment, as of April 2011 , are the Naval Education and Training Command , the Navy Installations Command , the Naval Meteorology and Oceanography Command , the Naval Information Warfare Systems Command , the Naval Facilities Engineering Command , the Naval Supply Systems Command , the Naval Air Systems Command , the Naval Sea Systems Command , the Bureau of Medicine and Surgery ,

12272-563: The static thrust of the -100/200, but the -220 has better dynamic thrust across most of the envelope. The F100-220 was introduced in 1986 and was installed on the F-15 and F-16, gradually replacing the -100/200. Seeking a way to drive unit costs down, the USAF implemented the Alternate Fighter Engine (AFE) program in 1984 (nicknamed "The Great Engine War"), under which the engine contract would be awarded through competition;

12390-536: The successful bombardment and capture of the city. This successful landing and capture of Veracruz opened the way for the capture of Mexico City and the end of the war. The U.S. Navy established itself as a player in United States foreign policy through the actions of Commodore Matthew C. Perry in Japan, which resulted in the Convention of Kanagawa in 1854. Naval power played a significant role during

12508-482: The treaty. The New Deal used Public Works Administration funds to build warships, such as USS  Yorktown  (CV-5) and USS  Enterprise  (CV-6) . By 1936, with the completion of USS  Wasp  (CV-7) , the U.S. Navy possessed a carrier fleet of 165,000 tonnes displacement , although this figure was nominally recorded as 135,000 tonnes to comply with treaty limitations. Franklin Roosevelt ,

12626-608: The unsatisfactory reliability, maintenance costs, and service life of the F100-100/200, Pratt & Whitney was eventually pressured into upgrading the engine to address these issues. The Air Force also began funding the General Electric F101 Derivative Fighter Engine , which eventually became the F110, as a competitor to the F100 to coerce more urgency from Pratt & Whitney. The result of Pratt & Whitney's improvement efforts

12744-604: The years much as the Commander of the Carrier Air Group/Wing (CAG) does not work for the carrier commanding officer, but coordinates with the ship's CO and staff. Some Marine aviation squadrons, usually fixed-wing assigned to carrier air wings train and operate alongside Navy squadrons; they fly similar missions and often fly sorties together under the cognizance of the CAG. Aviation is where the Navy and Marines share

12862-588: Was a major participant in the Korean and Vietnam Wars , blockaded Cuba during the Cuban Missile Crisis , and, through the use of ballistic missile submarines , became an important aspect of the United States' nuclear strategic deterrence policy. The U.S. Navy conducted various combat operations in the Persian Gulf against Iran in 1987 and 1988, most notably Operation Praying Mantis . The Navy

12980-610: Was done by applying technology from the F100-PW-232 (see below), which in turn incorporated technology and advancements from the F119 program for the F-22, as well as (for -229EEP) from the F135 program for the F-35; the -229EEP incorporates updated turbine materials, cooling management techniques, compressor aerodynamics, split cases (top and bottom) and updated DEEC software. Deliveries of

13098-493: Was extensively involved in Operation Urgent Fury , Operation Desert Shield , Operation Desert Storm , Operation Deliberate Force , Operation Allied Force , Operation Desert Fox and Operation Southern Watch . The U.S. Navy has also been involved in search and rescue/search and salvage operations, sometimes in conjunction with vessels of other countries as well as with U.S. Coast Guard ships. Two examples are

13216-714: Was faced with a two-front war on the seas. It achieved notable acclaim in the Pacific Theater , where it was instrumental to the Allies' successful " island hopping " campaign. The U.S. Navy participated in many significant battles, including the Battle of the Coral Sea , the Battle of Midway , the Solomon Islands Campaign , the Battle of the Philippine Sea , the Battle of Leyte Gulf , and

13334-572: Was first fielded in 1992 on the F-16C/D Block 50; the engine would also power enhanced F-15E variants, starting with the F-15K for South Korea. A non-afterburning variant of the F110, designated the F118 , would power the B-2 stealth bomber and the re-engined U-2S reconnaissance aircraft. A variant of the F110-100 fitted with a 3-dimensional axisymmetric thrust vectoring nozzle, referred by General Electric as

13452-727: Was not until 1921 US naval aviation truly commenced. During World War I , the U.S. Navy spent much of its resources protecting and shipping hundreds of thousands of soldiers and marines of the American Expeditionary Force and war supplies across the Atlantic in U-boat infested waters with the Cruiser and Transport Force . It also concentrated on laying the North Sea Mine Barrage . Hesitation by

13570-570: Was similar to the F-14's originally intended F401 and provided a significant increase over the TF30's maximum uninstalled thrust of 20,900 lbf (93 kN). These upgraded jets were initially known as F-14A+ before being re-designated as the F-14B, as were new production aircraft powered by the F110. The same engine also powered the final variant of the aircraft, the F-14D. Proposed upgraded variants of

13688-538: Was successful in a number of engagements and raided many British merchant vessels, but it lost twenty-four of its vessels and at one point was reduced to two in active service. In August 1785, after the Revolutionary War had drawn to a close, Congress had sold Alliance , the last ship remaining in the Continental Navy due to a lack of funds to maintain the ship or support a navy. In 1972,

13806-482: Was the F100-PW-220, which eliminates almost all stall-stagnations and augmentor instability issues from the -100 as well as doubling time between depot overhauls. Reliability and maintenance costs were also drastically improved, and the engine incorporates a digital electronic engine control (DEEC). The -220 engine produces static thrust of 14,590 lbf (64.9 kN) in military (intermediate) power and 23,770 lbf (105.7 kN) afterburning, very slightly lower than

13924-816: Was upscaled from the F404 so that its thermodynamic cycle and thrust were better suited for a fighter engine. The convergent-divergent iris nozzle was also derived from the F404. The cancellation of the B-1A by the Carter Administration (in lieu of the Advanced Technology Bomber which became the B-2 ) meant a loss of business for General Electric, and provided further impetus to provide the F101X for
