The actual development of the aircraft On Mark Marksman was conducted by American engineers and designers based on the military version of the aircraft Douglas A-26 Invader, with the result that the design process itself was reduced only to optimizing the design of the aircraft and the technical implementation of the project, which reduced both development time and real cost aircraft, thereby creating some demand. However, due to the fact that the aircraft was actually a redesigned model of an American light bomber that existed as a surplus of orders unrealized in the US military, the production of On Mark Marksman aircraft was quite limited - in three years only 8 aircraft were created, of which, according to the 2012 year, only 5 aircraft were in operation.

Plane Project On Mark Marksman was designed exclusively for the commercial use of its private owners, since carriers do not fit the current model due to low passenger capacity, enough to limited space in the cabin.

On board, the On Mark Marksman can accommodate up to 10 crews, including two crew members and eight passengers (subject to the installation of additional seats), which fully satisfied private air carriers engaged in sightseeing flights, as well as private owners of this aircraft. If necessary, all the seats on board the aircraft could be quickly dismantled, and the aircraft could transport cargo with a total weight of up to 4447 a kilogram, which was also quite effective.

The powerplant of the On Mark Marksman aircraft consists of two Pratt & Whitney R-2800-CB16 / 17 "Double Wasp" radial piston engines developing aggregate thrust in 5000 hp, which gave the aircraft a high displacement speed of about 587 km / h. (maximum value). In addition, the aircraft On Mark Marksman is also able to overcome and sufficiently long distances, limited to 4180 kilometers, which in some cases surpasses newer models of twin-engine aircraft of a similar type.
