The U.S. Navy's front line, land-based maritime patrol aircraft, the Lockheed P-3 Orion is a highly capable anti-submarine warfare platform. Conceived as a replacement for the P-2 Neptune and P-5 Marlin, the P-3 first flew in 1961. It was loosely based on the design of the L-188 Electra passenger aircraft. Equipped with four Allison T56 turbo-prop engines, the P-3 has the speed of a fast propeller-powered fighter and a range of nearly 2,400 nautical miles. It can remain on station at 1500 feet for three hours with a range of 1,300 nm. The aircraft typically carries three pilots and a crew of eight. Armament capacity is up to 20,000 pounds and can include the AGM-84 Harpoon, AGM-84E SLAM, AGM-84H/K and AGM-65F Maverick. The P-3 has provided reliable service to the U.S. and its allies. In addition to Cold War submarine tracking, its missions have included enforcing the blockade of Cuba during the 1962 crisis, coastal patrols in the Vietnam War, and targeting of Iraqi naval elements during the Gulf War. Over the decades the P-3 has received several major up-dates, and more than forty variants have been developed. It is expected to remain in service for the U.S. Navy until at least 2013 when the P-8 Poseidon begins deployment. This pilot's manual was originally created by Lockheed and the U.S. Navy. It has been declassified and is here made available in book form.
