I was told I dont need them with the centerline propulsion unit, and although somewhat redundant, I'm inclined to put low HP propulsion units in isolated 1 ATM cans in the aft end of both. The forward ends would house high power lights for night exploration.</span></div>

The boat's mission requirements are photography/video, small object retrieval, and a lift bag deployment capability. Size of the forward viewport(s) are not yet determined, but forward visibility is hamperred in any case and would need to be supplemented by technology. Note the Gamma inspired side ports.</span></div>

This means very fine bouyancy control, so a large volume centerline VBT is envisioned. The dive planes are fixed for most ops, used for dynamic dive control at speed and at periscope depth, (a dangerous place to be), the periscope uses micro cams.</span></div>

Those are in fact saddle tanks in this view and would be vented together in the sail. Aft MBT would end just forward of the housing that encloses the main propulsion unit.</span></div>
