Under a secret effort designated Southern Star I, China Airlines began its clandestine airdrop operations over North Vietnam since 1965. After CAL lost 49 crewmen and 10 airplanes, Southern Star III was taken over by the ex-34th Squadron staff in 1968. Known as the Black Bat 34th Sqn, the 34th was a corps of CIA recon crewmen flew night missions over Red China, to drop agents and gathered signal intelligence around Communist military bases. During their 838 missions in 1953-67, in total 148 airmen were doomed, averagely only one men returned for every three. The calamity that have usurped the 34th, can best be described as sad paradigm bets due to shady mission planning from top brass and CIA.
Facing the P2V-7U deep-penetration unresisted , the Reds started deploying three flak groups in Liaodong Peninsula since September 1961, which was confirmed by the oblique shooting cameras of USAF U-2 from high seas. Among the new trio, No.3 was the most ferocious threat, including six 85mm companies and six 37mm companies for high and low altitude, respectively. Held up this scourge in briefing, CIA planners still issued the course of 11/06/1961 mission. In the previous night a Neptune endured dense barrage over Liaodong until it reached high sea. But the exhausted crewmen unconditionally obeyed their order to return to the death trap. Not all the Black Bat's sorties could be covered by their flight skill and stealth tactics. In just 30 seconds after being caught by search lights, multiple hits from the No.3 AA group blew up the P2V, it crashed at 300 meters east of Biliu River nearby Yunning Village. Most of the airplane exploded to pieces, all 13 crewmates perished. In average, each P2V sortie faced eight intercepts, and three or four passes per intercept, i.e. at least two dozens onslaughts commenced on every mission in the PLAAF records. Until 1964, three more Neptunes crashed with all hands on board, as well Flying Fortress and Invader loses.
During the Cold War, the Black Bat Sqn started its initial operational phase as the Technical Development Unit with 2 RB-17Gs. In mid-June, 1952, with its crewmen newly trained by the USAF in Japan, the Flying Fortress duo of the TDU which directly reported to the HQ of CAF, began stationed at the Xinzhu AFB. Right after the termination of deep penetration missions of the 8th BG’s PB4Ys, the intelligence electronics on the aging Privateers were retrofitted into the Fortress replacements, which continued the clandestine sorties. The 34th had endured blow after blow at the hands of flak and MiG, until its survivors continued to fight over North Vietnam in 1968.
