      Not sure about that ‘water-through-hinges’ concern.  Beyond the hatches on top and hard-patches, where would water intrude ?

      One the M1A2 weight a quick short-cut at http://en.wikipedia.org/wiki/M1_Abrams
      The point of LCU-F is to be able to deliver two if not three 68 short-tons M1A2 per LCU-F – not that anybody would want to put that many eggs in one basket.  The typical USMC MEU seems to have 4 M1A2s plus one recovery tank, plus 15 AAV-7 amphibious personnel carriers, a bunch of etc. etc.
      In the rarest of cases one LSD-41 could deliver at least 12 such tanks, if not 18 and thus up to 36 per two LSD-41s alongside the LHD with her 3 LCACs – all embarked at the base into LCU-Fs which then enter the LSD/LPD well-decks for global delivery, loitering, sudden assault. 
      36 Main Battle Tanks in one unannounced delivery would be quite potent indeed...
      Delivery of one MEU ‘First Wave’ at 15 concurrent surface-borne insertion-points is pretty ‘nifty’ as well, since currently not remotely doable.

      Why fly tanks ? 
      And where would you land them ?  Friendly heavy-duty airfields near the ‘theater’ ?
      And how would you avoid announcing your intentions, your numbers, caliber, capabilities ?

      Amphibious fleet-assets – some 30 ships ranging from 16,000ton to over 40,000 tons fully loaded – are designed to carry ‘everything’ aboard, incl. Marines in order to then deliver them via LCU, LCAC and/or perhaps LCU-F.  They may do so for years and never get to ‘pull the trigger’ - beyond exercises.   
      Currently they could have 8 ‘ARGs’ deployed at ay one time.
      Plus the carriers, destroyers, subs etc.
       
      Current policy is for the Navy and Marines to ‘fly in’ at most 10% of the force-weight, i.e. folks, lighter supplies, a field-piece or two, a truck or two etc. and that only from the LHD-flat-top and the LPD/LSD helo-pads – not from halfway around the world.
      The Navy can indeed deliver ‘slowly’ at 20 kts+ a great many tons of assault power to just about anywhere on the globe. 
      With LCU-F the First Wave could max out at over 2600 tons to land concurrently.

      Lot’s to ruminate over.
      Not your typical ‘small-craft’ forum topic !
      But part of national defense and thus suitable topic in a democracy....

      Could be some serendipity at work here.   I notice that the Marines and Japanese SDF are having a big exercise on the west coast to practice seaborne assault.  The big question with the LCU-F is “how will you keep the water from squishing up through all those hinged joints in the decks??”  ;-)

      Light assault troops, whether air or seaborne, have always had a problem with not having heavy weapons and armor to back up their punch.  Usually, if there is no armor in a US force it is because someone up the command chain didn’t want to authorize tankers to operate.  Clinton and the boys didn’t want armor in Mogadishu until after the “Black Hawk Down” incident showed that they should have had some.  As a result of that, we built a company sized quick reaction armor force capable of flying anywhere in the world in chop-chop time.

      But a force like that needs some deep runways to land in on.   C-17s with a battle ready M1A2 Abrams tank on board are not light weight.  The tank weights around 82 tons by itself.  So sealift is vital to send heavy equipment to un-improved areas where airlift can’t operate.

      Good luck with your efforts, Sue.
