UV-18A Twin Otter

The UV-18A 'Twin Otter' is the military version of the DeHavilland DHC-6 with optional float and ski fittings. The aircraft have crew and passenger oxygen systems and a navigation/communication package which gives it an all-weather capability. It has a cruise speed of 150 knots, a service ceiling of 25,000 feet and a range of 700 miles. Designed to replace DHC-3, DHC-6 made its first flight on May 20, 1965. This general-purposed civil and military transport, used by regional airlines in Alaska and other areas with short or rough runways, entered production early in 1966. By September 1982, over 800 DHC-6 were built, and by the end of production in 1988 a total of 844 aircraft were built for various military and commercial customers.

Airlift support for the US Air Force Academy cadet parachuting program is provided by three UV-18B aircraft which carry a pilot, copilot and up to 17 jumpers. These Twin Otters are the only three owned by the Air Force. In the MSAG Antenna Test and Evaluation conducted 25-31 August 1998 in Marina CA, the NPS/CIRPAS UV-18A Twin Otter provided the surrogate UAV function during a test and evaluation of the MSAG ITT Antenna under development by the Joint Projects Office. Imagery from the Twin Otter was received by the multi- source capable antenna based at the CIRPAS facility in Marina. In the Alaska Army National Guard the UV-18As have been replaced by the C-23B+.
