Ten B-52s were shot down over the North and five others were damaged and crashed in Laos or Thailand. Thirty-three B-52 crew members were killed or missing in action, another 33 became prisoners of war, and 26 more were rescued.[93]

The United States is preparing to deploy up to six nuclear-capable B-52 bombers to northern Australia, a provocative move experts say is aimed squarely at China.
Becca Wasser from the Centre for New American Security says putting B-52s in northern Australia is a warning to China, as fears grow Beijing is preparing for an assault on Taiwan.
"Having bombers that could range and potentially attack mainland China could be very important in sending a signal to China that any of its actions over Taiwan could also expand further," she says.
The bombers are part of a much larger upgrade of defence assets across northern Australia, including a major expansion of the Pine Gap intelligence base, which would play a vital role in any conflict with Beijing.
B-52H The B-52H had the same crew and structural changes as the B-52G. The most significant upgrade was the switch to TF33-P-3 turbofan engines, which, despite the initial reliability problems (corrected by 1964 under the Hot Fan program), offered considerably better performance and fuel economy than the J57 turbojets.[168][252]
The ECM and avionics were updated, a new fire control system was fitted, and the rear defensive armament was changed from machine guns to a 20 mm M61 Vulcan cannon (later removed in 1991–94).[251]
The final 18 aircraft were manufactured with provision for the ADR-8 countermeasures rocket, which was later retrofitted to the remainder of the B-52G and B-52H fleet.[255] A provision was made for four GAM-87 Skybolt ballistic missiles.
The aircraft's first flight occurred on 10 July 1960, and it entered service on 9 May 1961. This is the only variant still in use.[3] A total of 102 B-52Hs were built. The last production aircraft, B-52H AF Serial No. 61-40, left the factory on 26 October 1962.[256]
