this thread is for all those weapon systems that were developed and almost made it to the troops in the field but for one reason or another never quite got there. Any posts are to have the country of origin and a short history of the system please

USA:

The Dornier Do 31 was a West German experimental VTOL jet transport built by Dornier. The Do 31 was designed to meet a NATO specification (NBMR-4) for a tactical support aircraft for the EWR VJ 101 VTOL strike aircraft designed under the NATO contract of BMR-3. The project was cancelled in 1970 owing to high costs, technical problems and a change of requirement.

The CAC CA-15, also known unofficially as the CAC Kangaroo, was an Australian propeller-driven fighter aircraft designed by the Commonwealth Aircraft Corporation (CAC) during World War II. Due to protracted development, the project was not completed until after the war, and was cancelled after flight testing, when the advent of jet aircraft was imminent.

I wish a game developer would make an alternate reality Cold War turning hot with this kind of projects.

The Convair Model 48 Charger was a prototype light attack and observation aircraft of the 1960s, developed to meet a requirement for a dedicated counter-insurgency (COIN) aircraft. It was a two-seat, twin-boom aircraft powered by two turboprop engines which lost out to the North American Rockwell OV-10 Bronco of similar layout, only a single example being built.

The irony is that this was all posted just prior to the obsolecence of the battleship.

Erprobungsträger mit 3-achs Stabilisiertem Turm a German project from 1966.

A Sherman’s stabilizer stabilized the tank’s gun in the vertical plane, while a Centurion Mk. 3’s stabilizer stabilized the gun in two planes, vertical and horizontal.

This vehicle, the only one of its kind, featured a heavily modified Leopard 1 hull and a turret that was stabilized in 3 planes- not only able to compensate for vertical and horizontal motion, but also for roll on the axis of the main gun. It also included an auxiliary 20mm autocannon, as many other western tank designs did at the time.

The advantages of the 3-axis stabilization system were ultimately not worth the cost and engineering difficulty of implementation, especially compared to a simple bolt-on 2-plane system
