Lockheed Martin hopes to have South Korea’s purchase of the S-3 Viking approved in June. Seoul’s purchase of the maritime patrol and and submarine hunter is also acting as a barometer for other countries, including Vietnam, and two other nations. The comments were made by the company’s director of maritime patrol programs, Clay Fearnow at this year’s FIDAE 2016 expo in Chile. Renewed interest in the plane by South Korea, as a supplement to its order of P-9 aircraft, has given it a new lease on life since the 2009 divestment by the US Navy.
The S-3B Viking carried out the US Navy’s carrier-based sea control mission. The S-3 was originally designed in the early 1970s to replace the S-2 Tracker. The new aircraft had a sophisticated anti-submarine warfare sensor suite. It was nicknamed by its aircrews as the Hoover.
The S-3A variant was replaced in the early 1990s by the S-3B. This incorporated upgrades such as the APS-137 inverse synthetic aperture radar and the AGM-84 Harpoon anti-ship missiles.
In 2009 the S-3B Viking was retired from the US Navy’s front line service, though some of these aircraft were still used for secondary duties. These aircraft were finally retired in 2016 after more than 40 years of service. The Viking was retired without proper replacement. Its missions were taken over by the P-3C Orion, various SH-60 Seahawk series helicopters and F/A-18E/F Super Hornets.
