* President Joe Biden's 2022 budget would continue a trend of providing a growing portion of the military's resources to air and naval forces--raising questions about how low the Army's topline will go as a share of the Pentagon's fiscal pie in coming years.

Air and naval forces went from a 48 percent share of the defense budget in 2013 to a 52 percent share in 2021, while the portion going to ground forces shrank from 35 percent to 32 percent during that same time period, said Travis Sharp, a research fellow at the Center for Strategic and Budgetary Assessments.

"The fiscal year '22 request continues this trend, providing 53 percent of the topline to air and naval forces and 31 percent of the topline to ground forces," he said during a recent panel hosted by CSBA. The Air Force's share has been increasing the most, while defense-wide accounts have remained relatively constant, he added.

The shift coincides with the United States' refocus on great power competition with China, which the Pentagon has identified as the primary "pacing threat," he noted.

"Most experts agree that military competition and conflict with China will primarily--although not exclusively--occur in air and naval" domains, Sharp said.
