? 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.
Cost Snapshot (ballpark)
| Metric | Upgrade Old F-16 | Buy New F-16 Block 70 |
|---|---|---|
| Per Jet Cost | $10–20M | $70–80M |
| Lifecycle Left | 10–15 years (avg) | 30+ years |
| Maintenance (per year) | Higher (older jets) | Lower (new tech) |
| Combat Capability | High (if fully upgraded) | Higher baseline |
| Time to Field | Faster if local MRO | Longer lead time |
