Re: Litton Launching Platform model.
I'm proud to share some photos of my completed model of the Litton Launching Platform from 1975. The platform is part of the then Litton's West Bank ship building facility.
FYI, some general characteristics of the real platform:
Length 640 feet.
Width 212 feet.
Capacity 55,000 tons.
The launching platform is positioned next to the launching area and rests on a grid or shelf so that the tracks on the pontoon line up in three dimensions with the tracks on the building area. One entire wing wall of the pontoon is removed and the ship to be launched is transferred to the launch platform. This wall is then replaced, and the platform is floated off the grid. The platform and ship are then hauled by chain and winch out into deep water with the platform ballasted down leaving the ship to float off and towed to be fitted out at the Yard (Information from various online sources).
In March 1975, the platform broke into two and sank in 72 feet of water, prompting a brave salvage effort by the USN and Shipyard.
My model is constructed from Evergreen plastic sheet offcuts and scrap balsa wood. The balsa forming the base of the pontoon and laminated with the styrene sheets. In 350 scale the model ended up being quite big and used up lots of paint. Photos of the platform from that time show extensive machinery, piping, and wiring etc. fitted to the platform that I just can't find the details on to model without detailed plans. Nonetheless, I'm pleased I've finally attained a floating dry dock. I might get round to make the model look weathered and beaten up.
Any comments welcome!
