The correct answer is the CASA C-101 Aviojet.
The aircraft was designed in response to a Spanish Air Force requirement in 1975 for a jet trainer to replace its aging fleet of Hispano Ha.200s and Ha.220s. Like many European jet trainers, it was also to have a limited attack capability. CASA sought technical assistance from MBB and Northrop and produced a design along largely conventional lines, the only surprising feature being a large internal weapons bay beneath the rear cockpit, allowing for a wider variety of armament to be carried than the underwing pylons alone would allow. Alternatively, this bay can be used to carry reconnaissance equipment. The aircraft is designed in a modular fashion to ease manufacturing and maintenance.
