Sorry for the delay, we have been really busy with the project. Attached are 
some photos of the tank test model of the VAS. The pressure hull is complete 
and certified as well as the hydrodynamic envelope. Assembly will take place 
in Jan.. I will be sending you additional pictorials as they are edited. We 
also built a wire frame for the seating and wiring of the pressure hull. This 
saved us over two months construction time. Something to think about if you 
ever are asked. We were able to do all the wiring and plumbing while the 
pressure hull was still in pieces at the weld shop. I will send you those 
later. Once again, sorry for taking so long,
