Rockwell’s “Delta Spanloader” bomber

In 1978, Rockwell produced the final report on their “Innovative Strategic Aircraft Design Study” for the USAF, which Boeing and Lockheed also worked on (separately). Rockwell’s study included seveal unconventional bomber configurations, intended to fulfill different roles… they had a design for minimum cost, a design for supersonic penetration of enemy airspace, a spanloader for minimum weight, a spanloader with a built-in laser weapons system for defense against missiles and aircraft… and a delta-winged spanloader concept for maximum stealthiness.

The stealthy design, the D645-4A, largely looks pretty good in that respect, except for the vertical stabilizers; the design would do better with canted stabilizers or, better yet, no stabilizers at all.
