Guys I was thinking of sea state, RFA Lioness left Falklands  the same time as the fleet on return after action, she maintained 21 knots and arrived in UK 14 days ahead of the frigates and destroyers. Container ships maintain 20+ what ever the weather. The best escorts in the last war were the auxiliary carriers with swordfish. But I suppose what matters nowadays is showing the flag. Though I suppose the Nuc hunter killer subs would do good at it as they can do in excess of 30kts below what ever the weather and can kill subs as well as surface ships, though not aircraft. A friend of mine made a good suggestion missle launchers in iso containers, load them on and off merchant ships as required. But the 31's do seem to have good lines and as to the 57mm a/a is what is probably more useful than the old Vickers 4.5 which was never that special.

Yes, but surely size matters? The bigger vessels can just bash on regardless while the smaller ones, whatever their nominal top speed, have always been more affected by bad weather. Plenty of instances in WW2 when capital ships outstripped their escorts which in some cases had to turn back.Colin

The Iver Huitfelt ships are pretty big to be honest, they’re almost the size of a 45 and definitely more seaworthy than a 23. And if a 23 can escort people okay then I’m sure the arrowhead can.


As for modular weaponary, it’s the in thing. They love sticking Phalanx on stuff because all it really needs is a power supply and a control desk. Sadly the LPDs have lost their goalkeepers for Phalanx, for this reason, so I’d say that if it was required to arm merchant ships they’d just crane a Phalanx on, probably ex-Centurion ones at a guess.

I do not disagree with anyone, the only info on these boats are their weaponry and artist pics of them. But I imagine in future the main threats are subs, which are countered by a hunter killer sub and A/S helicopters, and aircraft countered by aircraft A/A weapons. Though these new supersonic missles that the Russians are boasting of are real game changers, not yet heard of a counter to them yet! But if it is in cost 5 for the price of 1 of the others lets have 30 of them to show the flag and carry out gun boat diplomacy. The tanker incident in the Gulf a few weeks ago shows the weakness of one or two boats in a large sea area.

Could always design a ship that can submerge like a sub for when a mach 3 missile inbound, even as it is descending it will produce a smaller target on the way down   %) {-)

Brilliant idea, sure the M.O.D would give a grant to research the idea. Remember talking to a scientist at Portland ASWE who was developing a high speed missile/torpedo, fired from a submerge platform on the seabed. I saw the models and I believed St Margarets did a trial for it once, but like all these good ideas it fell by the wayside due to finance cuts.!  ok2 :}

I know a multi-role vessel, the stern and bow areas have the electronic warfare parts in watertight sealed compartments the centre area is kept clear to allow for the recovery of other vessels by diving and having the boats berth on top, also as it transits to another area of operations this allows the navy to save fuel with one carrying the other, if need be, the centre area could be loaded with tanks, trucks or containers, or better still watertight containers containing the stores / vehicles, the air in the containers is removed to remove buoyancy and illegal hitchhikers. if the vessel has to submerge then the containers don't hinder this.   {-)  Oh and during no combat times, do some commercial work to supplement the naval cuts

Brilliant conception, you must make a model for Wickstead. Instead of modelling past and present why not do the future, should be fun. {-) %%

Didnt many of the frigates and destroyers coming back have battle damage and patched up water line holes in them so would have travelled slower?

Cannot finish the Victory, so what chance of starting this concept boat  :embarrassed:

Warspite never say die as they say, have a similar job with Endeavour, finally got it down and I am determined to finish it by next spring and I have just got out my Lesro kit of the Sun21to do after 15 years in the attic. To Jay s query there was no battle damage just smaller lightly built vessels cannot punch through a seaway like bigger heavier vessels, you see Jay a cubic yard of water weighs one ton, so a large wave of several hundred cubic yards of water has quite an impact on a hull, without the flexing off the hull passing over waves and straddling gullies between waves. So the larger and stronger the hull the bigger the waves they can handle. The big container boats put the hammer down when clear of the English channel and usually do not ease up until next port off call like Singapore at 21 to 30 knots depending on the vessel. Though this explains why damage an loss of containers at sea used to be more common than people realised.
