Project 775M. The propulsion system provides a maximum speed of more than 15kt and range of 5,000nmi. The vessel has a conventional "V" shaped bow at one end and a ramp at the other. However, there is a hole which is deliberately provided in the ship's hull: the stern tube. The patented SLV was a result of focusing on possible answers to the operational problems of conventional landing craft. The proven successful solution to the landing craft was the Stern Landing Vessel. Australian company Sea Transport’s Stern Landing Vessel boasts the sharp bow of a highly seaworth ship with a ramp on its stern. This facility is sometimes used to control aircraft speed in steep descents, or to taxi backwards when on the ground. Speed: 12 . But in early 2020 the fleet operates just 32 amphibs, including nine big-deck assault ships. But that could cost $75 billion over 30 years and would do nothing to change the Navy’s tendency to concentrate its capabilities in a relatively small number of big, expensive ships. Sea Transport emphasizes its ability efficiently to build stern-landers at a wide variety of shipyards. To that end, I would like to give credit to Sea Transport for the concept of a wonderful landing craft. Syndication © Copyright Military Leak 2020, All Rights Reserved. Brian Metcalf, the San Antonio-class program manager, asked the audience at the same 2019 industry event to imagine a different construct than the three-ship amphibious ready group, or ARG, that currently dominates Navy and Marine force-planning. Commercial applications for the SLV are similar to conventional landing craft; however the SLV design has overcome the primary problems associated with … This hole is located at the aft of the ship and is necessary for the propeller shaft to pass through and connect with the propeller to the ship's engine. Helicopters can develop thrust in any direction, … This way the ship can travel efficiently in heavy seas … Powered by triple Detroit 8V71 main engines rated at 375 hp each. Could this be it? That concentration leaves the fleet vulnerable to Chinese missile barrages.

The LST is powered by a combined diesel (CODAD) propulsion system. Speaking at a defense industry event in Maryland in mid-October 2019, Capt. The ship’s shallow draft would allow it to back itself onto a beach for rapid loading and unloading. Most jet airliners and some transport aircraft use astern propulsion (more commonly termed 'reverse thrust') to slow down after landing, reducing the load on the wheel brakes and shortening the landing rollout. Brilliant Stern Loading Landing Craft Engineering really shines when we find solutions problems and improve performance. Fourth, the traditional landing ship has landed at the bow, but the propeller is at the stern. A hydraulic pedestal crane, load rated to 6 tons, is mounted forward with deckhouse and machinery spaces located aft. In short, the Stern Landing Vessel is more stable, more efficient and more comfortable than a landing craft is, while still being able to beach itself. “[H]owever, the SLV design has overcome the primary problems associated with conventional landing craft, including: poor head sea capability due to bluff bow ramp, dramatically reducing speed; poor visibility due to bow ramp; crew discomfort and fatigue due to location of accommodation directly above machinery spaces; inadequate power available when de-beaching due to propellers working inefficiently astern, and the need to overcome the forefoot suction effect.”. Round out the group with inexpensive Stern Landing Vessel and escorts, and the fleet might discover a useful capability that’s cheaper than the current ARG and helps it to spread out its forces to better avoid Chinese missiles. Planning for amphibious operations in the European and Pacific theaters identified the need for specialized ships and landing craft to load and unload military cargo on unprepared beaches ... 8 ft 2 in (2.49 m) bow 14 ft 1 in (4.29 m) stern. This helps ship owners to achieve immediate and significant cost reduction and increased reliability of their stern tube systems. The well-dock has a wide stern ramp for loading and off-loading equipment and troops.
