Second prototype taxies past the hangers.

Development:

The OA-16 Kala was first proposed in late 2019 to the Saltwater Foreign Service Corps as a replacement for their FA-12 Razorback strike fighters, which were unsuited to the counter-insurgancy operations which the SWFSC was tasked with flying. The new aircraft was to be powered by twin turboprops and be capable of reaching 400 mph, with at least three weapons hardpoints.
.
The first unarmed prototype first flew from NovrdLisch Aerodrome in early 2020. Inital handling reports from the test pilots was favourable, with the Kala being stable at all speeds and fully aerobatic. Due to the narrow-track undercarriage the aircraft was found to be unstable during taxying, so a gyroscope system was fitted in the engine nacelles, completely solving the problem.

The second prototype flew a week later and, unlike the first prototype, featured five weapons stations, guns and armour. No serious problems were reported and the first production aircraft joined 1 Squadron, Foreign Service Corps, on the 13th of January.
.
Production aircraft feature a number of improvements over the prototypes, including an advanced FLIR system and an avionics package in the centre fuselage with a number of additional communications systems.

The Kala has proven a popular aircraft on the export market, with sales being made to the East Hamalian Air Force, Ardonian Air Force, Seigfried Aerial Crusaders, Brightneau Air Force and Parshain Air Force. At home, the Kala serves with both the Foreign Service Corps and the Saltwater Air Force. 498 Kalas have been built, including the two prototypes.
.
The Kala was first deployed on combat operations to Ardonia to fight rebels in that country, but the deployment was cut short with the outbreak of the Consador invasion. During the initial withdrawal from the country the Kalas harassed the advancing mechanized divisions with some success.
.
The OA-16 Kala is available for export at a price of $700,500 per unit!
