User:Swb/Constellation-A Base Design Proposal

The original Constellation is a 2290s design, which means T-1 frames. The 750kt cruiser frame is T-2. Working from a base Constellation design and ignoring refit costs, a Constellation-A design was produced with 2314 technology, as 2314 that was the research available when the Constellation refit was proposed in the 2315 MWCO.

Without subframe adjustment, this design would exceed power generation by 0.86 units and internal weight by 2.82 kt. Closing that gap requires subframe adjustment to T0, which is not unprecedented as it is used in the Excelsior base design. A design without subframe adjustment is

However, the design presented with the engineering subframes (including hull and warp) made T0 is recommended.

As per most fiat to designer transitions, it ignores excess BR cost due to the move of nacelles from internal to external. It exceeds canon statistics by 5 SR and undercrews by 1E.
