陸軍への移管

重量問題の言及

> The Army has modernized its tanks ahead of the Marine Corps.
> The most updated version is the M1A2 Sepv3 Abrams tank.
> That tank weighs 66 tons as a basic package and can come in at more than 80 tons with certain active protection systems equipment necessary for the modern battlefield.
> The upgraded Abrams runs over the weight limit for the Navy’s -ship-to-shore connector, or SSC.
>
> The existing Navy landing craft air cushion, or LCAC, could carry a single tank, without upgrades, ashore at that weight limit.
> The LCAC maximum speed is 40 knots with a full load, while the SSC can run at 35 knots or faster.
>
> Another option for transporting tanks is the landing craft utility class 1700.
> This vessel would be able to carry two M1A1 tanks. Though the LCU 1700 would still be difficult for early-stage forcible entry as it runs at a speed of 11 knots.
>
> That translates into the Marines only being able to carry one M1A1 (older model, no protection system) at a time on the LCAC or SSC and two tanks on an LCU but at very slow speeds.
> The carrying capacity further limits tank upgrades for Marine armor to keep pace with modern anti-armor threats.
