You know Harlequin..I was wondering the same about the quantity of steel ordered. I think this is for one ship..the first of the order for carriers.
Out of the 80.000 tons there will be alot of scrap..unusable portions to be used or scrapped for remelt. I am sure also that this 80,000 tons includes
different grades of steel. I think the initial design was for some 60,000 to 70,000 tons displacement ship.
You know I had forgotten that these ships used the jump ramp type launch to get the planes off.
I am not that familiar with this system in that I dont know if they can get a plane off with no foreward speed on this type of ship. I am sure also
that it depends somewhat on the load out of the plane..weapons, fuel, etc.
Also do these type ships ...take off thier aircraft light on fuel and heavier on weapons to get them off the deck and then quickly tank up once
airborne as do many of ours??
I have just never heard how effecient these jump ramps are verses the steam catapult.
I do know that steam catapults are more difficult and expensive to maintain than are jump ramps.. This is obvious.
Speed on our large carriers is not an issue. However the systems needed to maintain this are very expensive and also high maintenance. This high
maintenance also includes the cost of parts and training of personel.
I suspect alot of the appeal of these other systems is purchasing, design, and maintenance costs. A huge but also a very important consideration to
Our systems of this nature are well over half the cost of a capital ship of this type. For some reason our Navy is stuck on the concept of Nuclear
