   The model presented here is scaled to one inch to one foot. This gives the appearance of a huge model despite the fact that the wingspan is only thirty inches

   One of the remits of the limited warfare experience in Viet Nam and other Southeast Asia nation was the necessity for a new type of tactical airplane to, replace the vulnerable helicopters. This is the light armed reconnaissance airplane (LARA) specially designed for counter‑insurgency (COW) activities In view of the lack of adequate landing fields In these remote areas the proposed aircraft must also be capable of short take‑off and landing (S.TOL) operations from jungle clearings.

   After studying nine design proposals from various manufacturers the United states Navy . , . North American Aviation Corporation to build seven prototype aircraft for evaluation before the type is ordered in quantity for the Marine Corps. This twin engine twin boom airplane is functional ‑in every respect. The forward location of the cockpit and high wing provide virtually unrestricted visibility for reconnaissance missions while twin booms and high horizontal tail enable a truck to back up to the fuselage to facilitate transfer of supplies and equipment through the rear door for cargo carrying missions. A snail wing span mandatory because of the small fields from which the craft will be forced to operate.

   The new design can carry any of the following on a wide assortment of missions: six combat equipped infantrymen ‑as a transport; five paratroopers with full equipment for surprise raids; two litter cases with a medical attendants an ambulance plane. Assorted food or medical supplies or ammunition can be carried in the III cubic foot cargo compartment, when the craft serves as a cargo carrier. Sponsons or stub wings can be easily attached to the lower fuselage sides for the carriage of 2,400 pounds of external equipment including assorted bombs, napalm, and rocket clusters, plus four 7.62 nun machine guns, for attack missions Two 650 horsepower Garrett/AiResearch T‑76 turbo‑prop engines will enable this versatile airplane to attain 305 miles per hour at sea level. Loaded weight is 7,617 pounds, empty weight is 4.893 pounds. The engines were designed to operate on the same fuel as is used in army vehicles and the machine guns can fire the same ammunition used by the ground troops This enables the NA300 to operate along with the infantrymen without requiring special supply line& In addition, the unusual craft can fly from or to the decks of carriers without the use of arresting gear or catapult. Normal "crew" consists of the pilot; however, an observer is also carried during reconnaissance mission,
