The actual development of the On Mark Marksman aircraft was carried out by American engineers and designers based on the military version of the Douglas A-26 Invader aircraft, as a result of which the design process itself was reduced only to optimizing the aircraft design and technical implementation of the project, which reduced both development time and real cost. aircraft, thereby creating some demand. Nevertheless, due to the fact that the aircraft was actually a redesigned model of the American light bomber, which existed as a surplus of orders unfulfilled in the US armed forces, the production of the On Mark Marksman model aircraft was quite limited - only 8 aircraft were created in three years. of which, according to 2012 data, 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 aircraft can accommodate up to 10 people, including two crew members and eight passengers (subject to the installation of additional seats), which was quite satisfactory for private air carriers involved 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 carry cargo with a total weight of up to 4447 kilograms, which was also quite effective.

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