61-499: USS Lewis B. Puller (ESB-3) , (formerly USNS Lewis B. Puller (T-ESB-3) , and (T-MLP-3/T-AFSB-1) prior to that) is the first purpose-built expeditionary mobile base vessel (previously classified as a mobile landing platform, and then as an afloat forward staging base) for the United States Navy , and the second ship to be named in honor of Chesty Puller . The lead ship in her class of expeditionary mobile bases, she

122-456: A 52,000 sq ft (4,800 m ) flight deck with landing spots for two heavy-lift transport CH-53 helicopters, as well as additional deck space for two more CH-53s. Lewis B. Puller will also have a helicopter hangar, an ordnance storage magazine , underway replenishment facilities, and deck space for mission-related equipment storage. The addition of a flight deck makes the ship more top-heavy, and so less stable in heavy seas. The deck

183-573: A US$ 498M contract to General Dynamics NASSCO for the construction of second ESB variant, the as-yet unnamed T-ESB-4. This vessel will be built at the NASSCO shipyard in San Diego, California, with a scheduled completion date of 2018. On 15 January 2021, Secretary of the Navy Kenneth J. Braithwaite announced that ESB-7 will be named USS Robert Simanek in honor of PFC Simanek , a Marine who

244-633: A base for helicopters, MV-22 Osprey tiltrotors and even the F-35B stealth fighter, but the main role of the Ponce will be operating minesweeping MH-53E Sea Dragon helicopters. As of March 2013 "a number of variations" of the ESD were being considered; the ESB can fulfill many of the roles of a $ 2.5 billion "big deck" amphibious ship at a quarter of the price. Unlike the first two Expeditionary Transfer Dock (ESD),

305-576: A fleet wide usage is analyzed, significant logistical advantages are realized over time. Compared to diesel, it increases flexibility, versatility and efficiency, with capability of transforming to provide propulsion or electrical power more rapidly, which ever the situation dictates. In Norway gas electric hybrid propulsion is being used on a fleet of fully electric and plug-in hybrid ferries that cross fjords. Capable of travelling at 17-18 knots, these ships reduce total NO x by 8,000 tonnes per year and CO 2 emissions by 300,000 tonnes per annum. Saving

366-588: A form of IEP. A nuclear power plant produces the steam to operate turbine generators; these in turn power electric propulsion motors. Combined diesel or gas (CODOG) Combined diesel and gas (CODAG) Combined diesel-electric and diesel (CODLAD) Combined diesel–electric and gas (CODLAG) Combined diesel and diesel (CODAD) Combined steam and gas (COSAG) Combined gas or gas (COGOG) Combined gas and gas (COGAG) Combined gas and steam (COGAS) Combined nuclear and steam propulsion (CONAS) Integrated electric propulsion (IEP or IFEP) Eliminating

427-649: A full range of operational efficiency, a low-vibration quiet mode of operation, and some reduction in weight and volume relative to a diesel-only arrangement. In naval vessels, a pool of diesel generators are typically used to provide a base load and enough power to achieve cruise speed. The gas turbines are used to provide peak power for higher speeds and may be required to operate weapon systems with high power demands. In passenger ships, one or more gas turbines are used for fast cruising. The diesels provide reliable redundancy and an efficient source of electricity when in port, at anchor, or drifting. A diesel-electric system

488-522: A helicopter hangar , an ordnance storage magazine , underway replenishment facilities, and deck space for mission-related equipment storage, including up to four Mk 105 minesweeping hydrofoil sleds. GE Power Conversion will provide complete electric power, propulsion, and vessel automation systems for all ESB/ESD ships. This integrated power system (IPS) will also involve the ship's tandem propulsion motor powered by variable-frequency drives , harmonic filters , and high-voltage switchboards . Unlike

549-649: A new designator, similar to the L-class amphibious ships, S-class submarines, A-class auxiliaries and more. These three E-class ships were previously listed as seabasing ships in the Naval Vessel Register . In May 2011, General Dynamics NASSCO received a $ 744 million contract modification to fully fund the construction of the first two ships of the class, USNS  Montford Point (ESD-1) and USNS  John Glenn (ESD-2). Additional funding of $ 115 million for long lead time material and advanced design

610-578: A pleasant voyage, but is of less benefit to cargo ships . Because ships require electricity even when not underway, having all of the engines produce electricity reduces the number of engines needed compared to more traditional arrangements in which one pool of engines provides electricity and another pool of engines provides propulsion, reducing capital costs and maintenance costs. A typical integrated electric propulsion arrangement on larger (e.g. cruise ships) and naval vessels includes both diesel generators and gas turbines. On smaller vessels (which make up

671-525: A ship traveling off the coast of Somalia. Two SEALs went missing in the operation, and after eleven days of unsuccessful search and rescue, followed by search and recover, they were presumed dead by the Navy.

Puller was commissioned on 17 August 2017 in Bahrain , with her prefix changing from USNS to USS and her hull designation changing from T-ESB-3 to ESB-3. The Lewis B. Puller class of expeditionary mobile base ships differ from

793-401: Is an integrated electric propulsion system in which no gas turbines are used and all of the engines are diesel. A turbine-electric system is also possible using gas turbine generators. Some yachts use only gas turbines for integrated electric propulsion without any diesel engines. If electric propulsion is used via electric motor on shaft, or integrated into the main reduction gear driving

854-502: Is made with two operating spots and two parking spots, plus room to store two in the hangar. The mission deck's ability to submerge to launch landing craft was disabled and instead a crane, capable of carrying 11 metric tons (12 short tons) and moving a 41 ft (12 m) boat in up to sea state 3, carries watercraft, towed arrays, and unmanned vehicles into the water. The United States Navy ordered T-ESB-3 in February 2012 as part of

915-481: Is then used to power electric motors turning either propellers or waterjet impellors . It is a modification of the combined diesel-electric and gas propulsion system for ships which eliminates the need for clutches and reduces or eliminates the need for gearboxes by using electrical transmission rather than mechanical transmission of energy, so it is a series hybrid electric propulsion, instead of parallel . Some newer nuclear-powered warships also use

976-734: The Lewis B. Puller -class, or sub-variant, of Expeditionary Mobile Base (ESB) vessels serve to support special forces missions , counter-piracy/smuggling operations , maritime security operations , and mine clearance , as well as humanitarian aid and disaster relief missions. In order to support these extended roles, the ESBs will have military detachments in addition to the civil service mariners. ESB vessels are designed to support low-intensity missions, allowing more expensive, high-value amphibious warfare ships and surface combatant warships to be re-tasked for more demanding operational missions for

1037-641: The Battle of Iwo Jima . Construction of the ship began in October 2015. It was christened on 21 October 2017 and delivered to Military Sealift Command on 22 February 2018 and entered service the same day. ESB-5, the fifth vessel in the class, and the third ESB variant, began construction in January 2017 at NASSCO. Effective 4 September 2015, U.S. Secretary of the Navy Ray Mabus officially announced

It was anticipated that T-ESB-4 would be assigned to the Pacific Ocean, and like the other ESD ships, will be operated by the Military Sealift Command . In January 2016, it was announced that T-ESB-4 would be named USNS Hershel "Woody" Williams , after a World War II Marine Corps infantryman who earned a Medal of Honor in

1403-525: The Persian Gulf in late 2016 or early 2017. On 14 January 2016, the Secretary of the Navy announced that Lewis B. Puller ' s sister-ship would be named Hershel "Woody" Williams during a ceremony in Charleston, West Virginia. Hershel "Woody" Williams was commissioned on 7 March 2020. On 10 July 2017, Lewis B. Puller left from Naval Station Norfolk for her first operational deployment to

1464-495: The U.S. Navy 's first two expeditionary transfer dock support vessels, Montford Point and John Glenn . These two ships act as floating bases or transfer stations that can be positioned off the target area. Lewis B. Puller and Hershel "Woody" Williams serve as expeditionary mobile bases to support low-intensity missions. This allows more expensive, high-value amphibious warfare ships and surface combatant warships to be re-tasked for more demanding operational missions for

1525-878: The Afloat Forward Staging Base (AFSB) variant of the MLP will be called Expeditionary Mobile Bases, or ESBs. The new designation followed a 31 August 2015 memorandum sent to Mabus by Chief of Naval Operations Admiral Jonathan Greenert . The design of Lewis B. Puller is based on the hull of the civilian Alaska -class oil tanker . Lewis B. Puller can be outfitted with support facilities for her minesweeping , special operations, and other expeditionary missions. An accommodation barge can be carried to support up to 298 more people, including special-operations teams. Lewis B. Puller ' s flight deck has landing spots for four heavy-lift transport CH-53 helicopters, plus deck space for two more MH-53s. The ship has

1586-605: The ESD. In March 2013 Chief of Naval Operations Jonathan Greenert showed PowerPoint of the ESD- Expeditionary Mobile Base (ESD-ESB), a proposed variant of the ESD with increased accommodation, a hangar and large flight deck on piers above the semi-submersible deck, This was first proposed in January 2012, around the time of the sudden announcement that USS  Ponce would be converted as an interim AFSB(I) (ESB). The ESD-ESB could be used to support special forces and intelligence gathering as

1647-493: The ESDs that lower the entire ship until their boat decks are awash, ESBs use cranes to raise and lower small boats of up to 11 metric tons (12 short tons) to the water from their mission deck. Lewis B. Puller is the first non-combatant ship equipped with the Navy's N-30 class passive fire protection system. The ship is equipped to support United States Air Force CV-22s on special ops missions. Feasibility tests began in 2014 and

1708-542: The Gulf of Mexico. During these, personnel and a wide range of vehicles, from Humvees to M1 Abrams tanks, were transferred to, then launched from Mighty Servant 3 , in conditions up to Sea State 4. The transferring cargo was later reduced to Sea State 3 conditions, after some design changes. In August 2010, the National Steel and Shipbuilding Company in San Diego was awarded a US$ 115 million contract to design

1769-707: The MV-22 Osprey tilt-rotor aircraft would be evaluated for potential operations on board the Expeditionary Mobile Base ESD variant. The testing and certification of MH-53E helicopters for minesweeping operations from ESB support ships was slated to begin during fiscal year 2016. Additionally, Captain Stevens noted that the F-35B STOVL strike fighter was not then being considered for ESB operations because of exhaust heat from F-35B damaging

1830-479: The Marine Corps announced its intent to retire the two ESD ships. Although they were cheap to buy compared to amphibious assault ships and demonstrated seabasing concepts, they are limited to connecting with sealift vessels at wave heights below three feet, and payload, fuel capacity and accommodation space were reduced to cut costs. This led to the decision to retire the ships to prioritize other vessels, such as

1891-503: The Marine Corps announced its intention to retire both ESD ships after less than a decade of active service, but this was rejected by Congress in December 2022. The ships were subsequently placed in reduced operating status. The Expeditionary Transfer Dock concept is a large auxiliary support ship to facilitate the ' seabasing ' of an amphibious landing force by acting as a floating base or transfer station that can be prepositioned off

The change was required by

2135-732: The U.S. Navy. In September 2015, the Navy decided to redesignate the MLP as the Expeditionary Transfer Dock (ESD) and the AFSB as the Expeditionary Mobile Base (ESB). The Navy plans to procure six Expeditionary Mobile Bases (ESBs) in total, with a fourth (ESB-6) ordered in FY2018, a fifth (ESB-7) ordered in FY2019, and the sixth and final ship (ESB-8) with an order date yet to be determined. In mid-2022,

2196-654: The U.S. Navy. These ESB variants are slated to operate in the Middle East and the Pacific Ocean. Like the first two Expeditionary Transfer Dock, the overall design of the T-ESB-3 and T-ESB-4 is based on the hull of the civilian Alaska -class oil tanker . Both ESB variants will be outfitted with support facilities for its mine-sweeping, special operations, and other expeditionary missions. An accommodation barge will also be carried to support up to 298 additional mission-related personnel. Their aviation facilities include

2257-442: The U.S. Navy. These ESB variants operate in the Middle East and the Pacific Ocean. Lewis B. Puller was initially operated by the Military Sealift Command with the prefix "USNS" and a crew of Department of the Navy civilian mariners. She replaced USS Ponce , the U.S. Navy's interim AFSB support ship. Lewis B. Puller (ESB-3) is the second ship named after Marine Corps Lieutenant General Lewis Burwell "Chesty" Puller . The first

2318-573: The USN requested a fourth ship in the FY14 budget of the National Defense Sealift Fund, and proposed that both T-ESB-3 and T-ESB-4 would be ESD-ESB variants. Congress rejected both requests on the grounds that Ponce could do the job and ESBs should in any case be funded out of the main Navy account. As of March 2013 the Chief of Naval Operations was still planning to buy two ESD and two ESD-ESB variants despite

2379-565: The United States Maritime Prepositioning Force . The first part of the trial consisted of the two ships transferring cargo between themselves while anchored in Puget Sound . After successfully completing this, the vessels sailed to San Diego , where cargo was transferred from Watkins to Mighty Servant 1 , then taken ashore by LCACs; slightly submerging the deck of the heavy lift ship allowed

2440-485: The capability was added before the ship's 2017 maiden deployment. The testing and certification of MH-53E helicopters for minesweeping operations from ESB support ships began in fiscal year 2016. The F-35B STOVL strike fighter does not fly from ESBs because its exhaust heat might damage the deck, Captain Henry Stevens, the head of NAVSEA 's Strategic and Theater Sealift program, said on 16 January 2014. The United States Navy ordered T-ESB-3 in February 2012 as part of

2501-605: The cost trade-off, the Vehicle Transfer System was scrapped in favor of skin-to-skin mooring of a host ship alongside the ESD, and the LCAC complement was reduced to three. The new design is 785 feet (239 m) long, with a beam of 164 feet (50 m), a top speed of over 15 knots (28 km/h; 17 mph), and a maximum range of 9,500 nautical miles (17,600 km; 10,900 mi).

Joint High Speed Vessel (JHSV) will be called Expeditionary Fast Transport, or EPF; the Mobile Landing Platform (MLP) will be called Expeditionary Transfer Dock, or ESD; and the Afloat Forward Staging Base (AFSB) variant of the MLP will be called Expeditionary Mobile Base, or ESB. The new designation was pursuant to a memorandum sent to Secretary Mabus from Chief of Naval Operations Admiral Jonathan Greenert dated 31 August 2015. In January 2020,

2623-466: The flight decks of U.S. Navy amphibious assault ships. Some outfitting and specialized equipment specific to the V-22 was needed to support it, but little engineering work or modifications to the ship needed to be done; upon Lewis B. Puller ' s deployment, it had been upgraded to support V-22 operations by Special Operations Forces. On 19 December 2014, U.S. Navy's Naval Sea Systems Command awarded

2684-492: The hovercraft to "'fly' aboard". A second series of tests was conducted off Norfolk, Virginia in September and October 2006, with USNS  Red Cloud and MV Mighty Servant 3 . This time, the ships were moored together while underway, during which vehicles drove from Red Cloud onto Mighty Servant 3 , then embarked aboard LCACs. In February 2010, Mighty Servant 3 joined USNS  Soderman for further trials in

2745-450: The laws of armed conflict. The Secretary of the Navy approved the commissioning of all ESBs following feedback from the employment of ESB-3 and expected employment of subsequent ships of the class. Prior to commissioning, the ESB class was limited to defensive actions during times governed by the laws of armed conflict. Post-commissioning, these ships have greater mission flexibility throughout the [range of military operations]. In mid-2022,

2806-414: The majority of IEP vessels) the engines are typically just diesel. The advantages of gas turbines include much lower weight. and smaller size than diesels of similar power, and much less noise and vibration , but they are efficient only at or near maximum power. Diesel generators have the advantage of high efficiency over a wide range of power levels. Using them in combination allows for the benefits of

2867-431: The mechanical connection between the engines and the propulsion has several advantages including increased freedom of placement of the engines, acoustical decoupling of the engines from the hull which makes the ship less noisy, and a reduction of weight and volume. Reducing acoustic signature is particularly important to naval vessels seeking to avoid detection and to cruise ships seeking to provide passengers with

2928-429: The more successful ESBs. The proposed retirement of the two ESDs was rejected by Congress in December 2022. Integrated electric propulsion Integrated electric propulsion ( IEP ), full electric propulsion ( FEP ) or integrated full electric propulsion ( IFEP ) is an arrangement of marine propulsion systems such that gas turbines or diesel generators or both generate three-phase electricity which

2989-441: The movements of both vessels while underway. A preliminary design by General Dynamics envisioned a ship that carried six LCACs, with the ability to turn around (dock, unload or load, then launch) two landing craft simultaneously from the stern. The ESDs were to host a brigade -size force, sail at 20 knots (37 km/h; 23 mph), and have a maximum range of 9,000 nautical miles (17,000 km; 10,000 mi). Each ship
