    With regard to helicopter the view must be forward to what the replacement of the current S-70/NH-90 classes will look like. Already there is the US program to replace the Blackhawks with the V-280 Valour and SB-1 Defiant in testing. Looking at these aircraft it is easy to see that the size will again increase with the next generation. The SB-1 Defiant is more that size of an AW-101 than that of a MH-60. Just this week the European helicopter manufacturers start their long slow path to the replacement of the current offerings.

    Additional considerations for Logs/Transport is that a variety of Combat and work vehicles are also carried ,and these also should not be weight limited other than by cranage or on / off loading ramps. Mowag Piranha V can be 15tonne combat weight.

    I note the design from Vard boasts a 70 tonne side and stern ramp. This would be strong enough for the majority of our heavy combat and engineering equipment. Multiple TEU expected to be carried on deck should be no more than 18 Tonnes each(normally focused on the 4 twistlock spots). If we assume the heavier equipment won't sit on the helideck, it would still have an expectation that a helideck should be able to easily manage a 20 tonne heli landing on it.
    Other vessel options offer a removable "lid" on the helideck to permit TEU or vehicle storage below. This would of course cause weight limitations.
    German 1: Private Schnutz, I have bad news for you.
    German 2: Private? I am a general!
    German 1: That is the bad news.

    I would avoid removable lids or even opening lids as they are operationally messy. Strength needn't necessarily be compromised as cropped transverse beams are compensated for by deep girders in the opening and usually strong pillaring from each corner. However to move cargo in or out would require everything to be dismantlable, again very messy. Especially with lifts and Cranes.

    If they can break they will, especially when exposed to the elements and not used very often

    Cheers for the info about the need for something more than the current design of the CANT.

    I found this article which gives some background and details;
