The Lockheed P-7 was a four turboprop-engined patrol aircraft ordered by the U.S. Navy as a replacement for the P-3 Orion. The external configuration of the aircraft was to be very similar to that of the P-3. Development had not progressed very much before the program was cancelled in July 1990. [1]
The Lockheed P-2 Neptune (designated P2V by the United States Navy prior to September 1962) is a maritime patrol and anti-submarine warfare (ASW) aircraft. It was developed for the US Navy by Lockheed to replace the Lockheed PV-1 Ventura and PV-2 Harpoon, and was replaced in turn by the Lockheed P-3 Orion.
The Lockheed WP-3D Orion is a production line variant of the P-3 Orion used by the Aircraft Operations Center division of the National Oceanic and Atmospheric Administration (NOAA) at Lakeland Linder International Airport, [13] [14] Florida. Only two of these craft exist, each incorporating numerous features for the role of collecting weather ...
The Lockheed P-3 Orion is a four-engined, turboprop anti-submarine and maritime surveillance aircraft developed for the United States Navy and introduced in the 1960s. Lockheed based it on the L-188 Electra commercial airliner; it is easily distinguished from the Electra by its distinctive tail stinger or "MAD" boom, used for the magnetic anomaly detection (MAD) of submarines.
After the cancellation of the EP-X Program, the U.S. Navy has planned to replace the EP-3E Aries II with the Northrop Grumman MQ-4C Triton unmanned aircraft and the MQ-8B Fire Scout unmanned helicopter. All P-3 Orion aircraft assigned to special projects squadrons (VPU) and all EP-3E Aries II aircraft are expected to fully retire by 2025. [11]
It is among the earliest precision guided air-to-ground weapons and the first to be mass produced. It first saw operational use in 1959 on the A-4 Skyhawk, but soon found use on the A-6 Intruder, F-100 Super Sabre, F-105 Thunderchief, F-4 Phantom II, F-8 Crusader, and P-3 Orion in both Navy and US Air Force service, as well as NATO allies.
The fourth stage of the Minotaur IV is the Orion 38 motor, which is also used in the Minotaur-C, Minotaur I, Pegasus, and Ground-Based Interceptor rockets. This motor performs the final orbital insertion burn for the payload. Like the first three stages, the Orion 38 also features thrust vectoring, with a 5-degree range of motion. [2]
The Lockheed WP-3D Orion is a highly modified P-3 Orion used by the Aircraft Operations Center division of the National Oceanic and Atmospheric Administration (NOAA). The aircraft are operated by officers of the NOAA Commissioned Officer Corps .
