Well, you could use them to ferry light armor (Jeeps and possibly M-16's). They could carry a 6000 lb vehicle.
DING DING! I like the option of being able to ferry a jeep and other smaller/lighter gv's (M3, M16, 251, M8?). This would extend the capture range of a CV fleet.I can only imagine the coding would be a nightmare and there are other priorities.
That would be nice to see landing GV on the Bish beach head !
Dont call me on this, but I'm pretty sure, that if someone upped a typical N1k or a Spit 16, you'd probably lose your Higgens boat a lot quicker than your LVT...
