升级是二手车；帮助大美销售老型号，MAGA

? Option 1: Upgrading Older F-16s (e.g., Block 30/40/50 to Block 70/72 or MLU)

Pros

• Lower acquisition cost: Upgrading costs ~$10–20 million per jet vs ~$60–80M for new.

• Familiarity: No new pilot training pipeline or support infrastructure needed.

• Life Extension: Service life extended by 3,000–8,000 flight hours (SLEP).

• Systems parity: With Block 70 upgrades, you get AESA radar (AN/APG-83), new mission computers, Link-16, advanced EW suites, and modern cockpit.

• Interoperability: Still fully NATO compatible.

Cons

• Airframe fatigue: Older jets may be near their design life limits even after upgrade.

• Upgrade time: Aircraft are out of service during modification (months per jet).

• Hidden costs: Refurbishment often runs into unexpected costs (corrosion, fatigue cracks).

• No stealth or low-RCS enhancements.

? Option 2: Buying New F-16 Block 70/72

Pros

• Brand new airframes: Full 12,000-hour life, modern wiring, no legacy issues.

• Cutting-edge systems: Comes with AESA radar, IRST, conformal fuel tanks, upgraded EW.

• High sortie rate: More reliable, lower maintenance burden short-term.

• Future-proofed: Easily integrates with 5th-gen data-sharing platforms (like F-35).

Cons

• Cost: ~$70–80M per aircraft (flyaway) + training + spares = big capital outlay.

• Lead time: New aircraft could take 3–5 years to deliver due to backlog.

• Political strings: U.S. export approvals and system lock-ins.
