Rounds explicitly states the US is using "F-22s" and "F-35s" to clear air defenses and is now transitioning to "heavier equipment, our B-1s, our B-52s" for strategic strikes. The active combat deployment of these specific airframes validates their utility and necessitates maintenance, sustainment, and potential replacement cycles. Lockheed Martin (LMT) is the prime for the F-35/F-22. Northrop Grumman (NOC) is the prime for the B-21 (the future bomber replacing the legacy fleet) and maintains heavy bomber fuselage components. LONG. Active usage in a high-intensity conflict acts as a "proof of concept" marketing event for foreign buyers and guarantees domestic sustainment funding. Political pressure to cease hostilities early could limit the duration of equipment usage.
