SAIC rolls out amphibious vehicle prototype for USMC

Science Applications International Corp (SAIC) has unveiled the first of 16 prototypes for the US Marine Corps' (USMC's) competitive Amphibious Combat Vehicle (ACV) 1.1 programme during a 21 February ceremony at the company's facility in Charleston, South Carolina.
SAIC partnered with Singapore Technologies Kinetics (STK) to submit STK's Terrex 2, which includes a V-shaped hull and space to carry 11 marines with a crew of three (to add additional room to carry two more marines would have required a redesign and added weight that the company deemed unnecessary).
"Tailored to meet [US] Marine Corps requirements, SAIC's ACV is an 8x8 wheeled, armoured amphibious vehicle with improved survivability, mobility, lethality, and C4ISR capability tailored to transport Marine Corps fighting units from ship to shore," the company said.
SAIC noted that its ACV 1.1's "engine and transmission offers 600 horsepower" and it is fitted with an independent suspension system, hydraulically driven propulsion systems with full independent thrust control authority, and water mode cooling solution that together allow "safe operation at Sea State 3 for ship-to-shore operational employment and through six-foot plunging surf".
The platform is built with "360-degree situational awareness, force protection through leading blast protection seats, and a V-Over-VTM hull design", SAIC said.
The USMC in November 2015 awarded competing engineering and manufacturing development (EMD) contracts to BAE Systems and to SAIC for ACV 1.1, and both companies are leading teams to produce 16 prototypes to be tested by the USMC beginning in early 2017.
BAE Systems partnered with Italian truck manufacturer Iveco Defence to submit a vehicle driven by a six-cylinder, 700 hp FPT Industrial Cursor 16 engine and with a suspended interior seat structure for 13 embarked marines, the company has said. BAE Systems first unveiled its prototype during a 13 December 2016 ceremony at the company's facility in York, Pennsylvania.
