26-887: The Martin P5M Marlin ( P-5 Marlin after 1962), built by the Glenn L. Martin Company of Middle River, Maryland , is a twin piston-engined flying boat that entered service in 1951, and served into the late 1960s with the United States Navy performing naval patrols. It also served with the United States Coast Guard and the French Navy . 285 were produced. Built as a successor to the PBM Mariner , it had better engines, an improved hull, and

52-719: A merger offer from the Wright Company , creating the Wright-Martin Aircraft Company. This merger did not function well, so Glenn Martin left to form a second Glenn L. Martin Company on September 10, 1917. This new company was headquartered in Cleveland, Ohio . In 1913, Mexican insurgents from the northwestern state of Sonora bought a single-seater Martin Pusher biplane in Los Angeles with

78-564: A powerful Centaur rocket upper stage, was used to launch the heavy Cassini space probe to the planet Saturn in 1997. The Cassini probe orbited Saturn from 2004 to 2017, successfully returning mountains of scientific data. The halting of production of the Titan IV in 2004 brought to an end production of the last rocket able to carry a heavier payload than the Space Shuttle, which itself ended in 2011. The Martin Company merged with

104-480: A single vertical fin tail. The XP5M Marlin prototypes were based on the last PBM-5 Mariners, the company designation being Model 237 . The type was heavily improved, again leading to the P5M-2 (Model 237B), which was redesignated SP-5B . A number of P5M-1 models were also used for training, designated TP-5A (after 1962). The Marlin was designed as a gull-winged aircraft to place the engines and propellers high above

130-666: Is located at the National Naval Aviation Museum at Naval Air Station Pensacola , Florida . This aircraft, BuNo 135533 , is believed to be the last remaining example of the Marlin. It is now displayed inside the new hangar (as of the spring of 2010) and much of the exterior has been restored. The restoration is being financed by the museum and the Mariner/Marlin Association. Data from United States Navy aircraft since 1911, Jane's all

156-758: The PBM Mariner and JRM Mars flying boats, widely used for air-sea rescue , anti-submarine warfare and transport. The 1941 Office for Emergency Management film Bomber was filmed in the Martin facility in Baltimore, and showed aspects of the production of the B-26. Martin ranked 14th among U.S. corporations in the value of wartime production contracts. The company built 1,585 B-26 Marauders and 531 Boeing B-29 Superfortresses at its new bomber plant in Nebraska , just south of Omaha at Offutt Field . Among

182-588: The Smithsonian Institution in Washington, D.C. As a display area at Smithsonian did not materialize, the aircraft was later relocated to the National Naval Aviation Museum at NAS Pensacola , Florida where it is currently on display. The final Marlin flight was carried out by VP-40, to San Diego Bay on 6 November 1967. Seven P5M-1Gs and four P5M-2Gs were built for the United States Coast Guard for air-sea rescue service, but they found

208-697: The Titan IIIA , the more-important Titan IIIC , and the Titan IIIE . Besides hundreds of Earth satellites, these rockets were essential for the sending to outer space of the two space probes of the Voyager Project to the outer planets , the two space probes of the Viking Project to Mars , and the two Helios probes into low orbits around the Sun (closer, even, than Mercury ). Finally,

234-628: The 1930s, Martin built flying boats for the U.S. Navy , and the innovative Martin B-10 bomber for the Army. The Martin Company also produced the noted China Clipper flying boats used by Pan American Airways for its transpacific San Francisco to the Philippines route. During World War II, a few of Martin's most successful designs were the B-26 Marauder and A-22 Maryland bombers,

260-819: The American-Marietta Corporation, a chemical-products and construction-materials manufacturer, in 1961, to form the Martin Marietta Corporation . In 1995, Martin Marietta, then the nation's third-largest defense contractor, merged with the Lockheed Corporation , then the nation's second-largest defense contractor, to form the Lockheed Martin Corporation , becoming the largest such company in the world. The Martin Company employed many of

286-676: The B-29s manufactured there were all the Silverplate aircraft, including Enola Gay and Bockscar , which dropped the two war-ending atomic bombs on Hiroshima and Nagasaki , Japan . On April 22, 1957, the company name was changed to the Martin Company. Postwar efforts in aeronautics by the Martin Company included two unsuccessful prototype bombers, the XB-48 and the XB-51 ,

312-734: The Martin Company merged with American-Marietta Corporation , a large industrial conglomerate, forming the Martin Marietta corporation. In turn, Martin Marietta in 1995 merged with aerospace giant Lockheed Corporation to form the Lockheed Martin corporation. Glenn L. Martin Company was founded by aviation pioneer Glenn Luther Martin on August 16, 1912. He started the company building military training aircraft in Santa Ana, California , and in September 1916, Martin accepted

338-688: The US Air Force required a booster rocket that could launch heavier satellites than either the Titan IIIE or the Space Shuttle . The Martin Company responded with its extremely large Titan IV series of rockets. When the Titan IV came into service, it could carry a heavier payload to orbit than any other rocket in production. Besides its use by the Air Force to launch its sequence of very heavy reconnaissance satellites , one Titan IV, with

364-689: The US Army's Pershing missile. The Martin Company was one of two finalists for the command and service modules of the Apollo Program . The National Aeronautics and Space Administration (NASA) awarded the design and production contracts for these to the North American Aviation Corporation. The Martin Company went further in the production of larger booster rockets for NASA and the U.S. Air Force with its Titan III series of over 100 rockets produced, including

390-734: The United States Navy were Market Time patrols of VP-40 . Maritime surveillance patrols began in February 1965 to locate small craft transporting supplies from North Vietnam to Viet Cong units in South Vietnam. VP-40 operated from seaplane tenders and patrolled off the Mekong delta between Phú Quốc and Vung Tau . The last U.S. Navy P5M, redesignated as SP-5B, was flown to NAS Patuxent River , Maryland on 12 July 1968 for interim storage pending construction of display area at

Martin Company In 1961,

442-734: The end of hostilities. A follow-up design, the MB-2 , proved successful; 20 were ordered by the Army Air Service , the first five of them under the company designation and the last 15 as the NBS-1 (Night Bomber, Short range). Although the War Department ordered 110 more, it retained the ownership rights of the design, and put the order out for bid. The production orders were given to other companies that had bid lower, Curtiss (50), L.W.F. Engineering (35), and Aeromarine (25). The design

468-595: The first known air-to-naval bombing runs in history. For the Dutch East Indies, several planes were delivered, with the first flight on November 6, 1915. It involved two Type TEs, six Type TTs, and eight Type Rs. Martin's first big success came during World War I with the MB-1 bomber , a large biplane design ordered by the United States Army on January 17, 1918. The MB-1 entered service after

494-464: The intention of attacking federal naval forces that were attacking the port of Guaymas . The aircraft was shipped on May 5, 1913, in five crates to Tucson, Arizona , via Wells Fargo Express , and then moved through the border into Mexico to the town of Naco, Sonora . The aircraft, named Sonora by the insurgents, was reassembled there and fitted with a second seat for a bomber position. The Sonora , armed with rudimentary 3-inch pipe bombs, performed

520-652: The marginally successful AM Mauler , the successful B-57 Canberra tactical bombers , the P5M Marlin and P6M SeaMaster seaplanes , and the Martin 4-0-4 twin-engined passenger airliner. The Martin Company moved into the aerospace manufacturing business. It produced the Vanguard rocket , used by the American space program as one of its first satellite booster rockets as part of Project Vanguard . The Vanguard

546-570: The planes difficult to maintain and surplus to requirements. They were subsequently transferred to the U.S. Navy, which redesignated them as TP-5A s and used them as training aircraft, since they had no provision for armament. The French Navy took delivery of ten former U.S. Navy Marlins between 1957 and 1959 to replace Short Sunderlands in maritime patrol service, based in Dakar , Senegal in West Africa. They were returned in 1964. One SP-5B

572-490: The rear. The P5M-1 was followed by 116 P5M-2 planes. These had a T-tail to put the tail surfaces out of the spray, an AN/ASQ-8 MAD boom at the rear of the tail-tip, no tail guns (the gun position replaced by the antenna for the AN/APN-122 Doppler Navigation Set), better crew accommodation, and an improved bow to reduce spray during takeoff and landing. The last flying boat operations of

598-471: The spray. Power was provided by two Wright R-3350 radial engines . The rear hull did not lift sharply from the water at the tail, instead rising up steadily, a Martin innovation; this gave the aircraft a longer base of flotation and reduced "porpoising" over waves. The prototype had nose and tail turrets with twin 20 mm (0.79 in) cannon in each, as well as a dorsal turret with two 0.5 in (12.7 mm) M2 Browning machine guns . The cockpit area

624-400: Was the first American space exploration rocket designed from scratch to be an orbital launch vehicle — rather than being a modified ballistic missile (such as the U.S. Army's Juno I ). Martin also designed and manufactured the huge and heavily armed Titan I and LGM-25C Titan II intercontinental ballistic missiles (ICBMs). Martin Company of Orlando, Florida, was the prime contractor for

650-948: Was the only standard bomber used by the Air Service until 1930, and was used by seven squadrons of the Air Service/Air Corps: Four in Virginia, two in Hawaii, and one in the Philippines. In 1924, the Martin Company underbid Curtiss for the production of a Curtiss-designed scout bomber, the SC-1 , and ultimately Martin produced 404 of these. In 1929, Martin sold the Cleveland plant and built a new one in Middle River, Maryland , northeast of Baltimore . During

676-577: Was the same as the Mariner's. It first flew on 30 May 1948. The first of 167 production P5M-1 aircraft was produced in 1951, flying on 22 June 1951. Changes from the prototype included a raised flight deck for improved visibility, the replacement of the nose turret with a large radome for the AN/APS-44 search radar, the deletion of the dorsal turret, and new, streamlined wing floats. The engine nacelles were lengthened to provide room for weapons bays in
