GonsaloTier 8, Heavy tank★ Premium tank
The project was developed at the Royal Military College in 1962. The tank had to have great mobility, good frontal armor, and a powerful gun with a magazine loading system. Originally the plan was to use a 160 mm gun with HE shells as well as nuclear warhead shells. During the latter's production, technical difficulties led to considering the name Gonsalo for a vehicle variant with a 120 mm gun using AP and HE shells. The vehicle turned out too complex and expensive to make, while the many innovations did not guarantee an advantage over the vehicles that were in development and production. The project was closed during the concept stage, with only general blueprints created. No prototypes were built.
