LOCKHEED VP-3A ORION

The P-3 Orion maritime patrol aircraft was based loosely on the Lockheed L-188 Electra airliner. Development of the P-3 began in 1958 and the prototype first flew in 1961. Since then the Orion has served as the primary long-range patrol and anti-submarine aircraft for the U.S. Navy, as well as for nearly 20 other countries. The VP-3A designation indicates that the aircraft has been modified for use as a VIP transport. Modifications include passenger seating, a galley, restroom, and baggage compartments.
