Beggar Shadow Mission The code name "Beggar Shadow" was used to describe the late-1960s Cold War reconnaissance program by the United States Navy that collected intelligence about and communications between Soviet Bloc nations while remaining safely (at least according to international laws) in international waters. At 07:00 local time on Tuesday, 15 April 1969, an EC-121M of the U.S. Navy's Fleet Airborne Reconnaissance Squadron One (
VQ-1) took off from
NAS Atsugi, Japan, on an intelligence-gathering reconnaissance mission. The aircraft, Bureau number 135749, c/n 4316, bore the tail code "PR-21" and used the radio call sign
Deep Sea 129. Aboard were 8 officers and 23 enlisted men under the command of
LCDR James Overstreet. Nine of the crew, including one
Marine NCO, were Naval Security Group
cryptologic technicians (CTs) and linguists in Russian and Korean. Its flight profile involved taking off from NAS Atsugi then flying northwest over the Sea of Japan until it came to an area off
Musu Point, where the EC-121M would turn northeast toward the
Soviet Union and orbit along a long elliptical track similar to that of a racetrack; once the mission was complete, they were to return to
Osan Air Base, South Korea. LCDR Overstreet's orders included a prohibition from approaching closer than to the North Korean coast. VQ-1 had flown the route and orbit for two years, and the mission had been graded as being of "minimal risk." During the first three months of 1969, nearly 200 similar missions had been flown by both Navy and U.S. Air Force reconnaissance aircraft off North Korea's east coast without incident. near
Wonsan and tracked them, assuming that they were responding in some fashion to the mission of Deep Sea 129. In the meantime the EC-121 filed a scheduled activity report by radio on time at 13:00 and did not indicate anything out of the ordinary, but this was the last message sent from the plane. Twenty-two minutes later, the radars lost the picture of the MiGs and did not reacquire it until 13:37, when they were closing in on Deep Sea 129 for a probable intercept. The communications that this activity generated within the National Security network were monitored by the EC-121's parent unit, VQ-1, which sent Deep Sea 129 a "Condition 3" alert by radio at 13:44, indicating it might be under attack. LCDR Overstreet acknowledged the warning and complied with procedures to abort the mission and return to base. Approaching from the northeastern coast at supersonic speed, however, the MiGs easily overtook the EC-121. The MiGs were armed with 23 mm cannons and
AA-2 Atoll missiles; the EC-121 was unarmed and without a fighter escort. At 13:47, the radar tracks of the MiGs merged with that of Deep Sea 129, which disappeared from the radar picture two minutes later. The MiGs had attacked and shot the plane down, and while the details of the incident have never been released to the public, it is assumed that an air-to-air missile was used as the North Korean press mentioned that a "single shot" downed the aircraft. ==Reactions==
