This would open up A LOT of capabilityBreaking Defence report that the MQ-9B can now be fitted with a STOL kit allowing its operation from carriers and assault ships.
Janes says that the MQ-9B STOL upgrade will utilise a wing and tail kit that can be installed on the platform in the hanger or on a flight line in less than a day. The kit can be removed to return the aircraft to conventional operations. The Mojave STOL prototype has been able to launch and recover in less than 300 ft during tests. The STOL kit suffers from a approximately 50 per cent drop” in endurance between the MQ-9B and MQ-9B STOL, however, the options for launching, recovering, and basing the aircraft are radically increased, changing the value for many missions.
FYI - The Canberra class 230.82 m /757 ft 3 in, the flight deck is roughly 80~85% of that but with added ski jump
