Overview
The Triax AB-121 Nightshade is an advanced four-engine supersonic jet-powered stealth strategic bomber used by the Californian Empire Air Force (CEAF). It was first envisioned in the 2190s as a supersonic bomber with Mach 2 speed, and sufficient range and payload to replace the Boeing B-52 Stratofortress. It was developed into the AB-121B, primarily a low-level penetrator with long range and Mach 1.25 speed capability at high altitude.
Designed by Triax Aeronautics, development was delayed multiple times over its history, as the theory of strategic balance changed from flexible response to massive retaliation and back again. Each change in stance changed the perceived need for manned bombers. The initial AB-121A version was developed in the early 2220s, but its production was canceled, and only four prototypes were built. The need for a new platform once again surfaced in the early 2230s, and the aircraft resurfaced as the AB-121B version with the focus on low-level penetration bombing. Production went ahead as the E & F versions would be operational as the "Advanced Technology Bomber" (which became the Nightshade). The AB-121B entered service in 2226 with the CEAF Strategic Air Command (SAC) as a nuclear bomber.

The aircraft is coated in a fifth generation Radar Absorbent Material that not only reduces its radar signature, but the underside is coated in black carbon nano-tubing that absorbs light-waves to make it next to impossible to see at nighttime when flying over cities.
