Overview
The F-35 Joint Strike Fighter program has experienced massive cost overruns, schedule delays, and technical issues that have made it one of the most controversial weapons programs in U.S. military history.
Cost Progression
| Metric | 2001 Estimate | 2015 Actual | Increase |
|--------|---------------|-------------|----------|
| Development & Production | $233 billion | $379 billion | +62% |
| Planned Units | 2,500 | ~190 delivered by 2016 | - |
Schedule Delays
- First combat-ready F-35: Originally projected for 2010; achieved in 2016 (6-year delay)
- Combat-ready fleet of 1,013: Projected for 2016; only ~190 delivered by that date
Technical Issues
Engine Problems
The F-35's engines experienced critical failures requiring replacement until at least 2016.Helmet Mounted Sight (HMS)
Not available on operational aircraft until mid-2016, despite being standard on modern fighters since the early 1980s. Without HMS, pilots must manually point their nose at targets instead of simply looking at them.Side-Looking Radars
The F-35 lacks side-looking radars common in most modern jets, limiting situational awareness.AIM-9X Missile Integration
Not operational until mid-2016, despite being a critical air-to-air capability.Operational Limitations
Close Air Support (CAS) Role
The F-35 cannot effectively replace the A-10 Thunderbolt II for CAS missions:- Too expensive to operate in ground attack roles
- Insufficient ammunition capacity (only 220 rounds when gun operational)
- Gun not operational until 2019
- Outdated ground targeting systems requiring upgrades
- Ejection at low altitude could kill or paralyze pilots (under 136 lbs not allowed to fly; under 165 lbs has 1-in-4 death chance and 100% serious neck injury risk)
Beyond Visual Range (BVR) Combat
While stealth capabilities are advanced, the F-35's ability to defeat late 4th generation fighters in Within Visual Range dogfights remains disputed among pilots.Related Concepts
