We hear that the Air Force plans to change its vocabulary when describing forces that are few in number yet heavily used. Such assets have been termed LD/HD, for low density/high demand. The new term would be LS/HD—limited supply/high demand.
The Air Force overall reduced its size by 120 aircraft in fiscal year 2021, but kept about the same number of fighter, bomber and attack aircraft, according to data supplied by the service. The F-35 fleet saw the biggest increase while the B-1B bomber fleet saw the largest decline.
