## FAQs
### Q: What is KH-8 Gambit 3?
A: KH-8 Gambit 3 is a family of U.S. reconnaissance spacecraft models designed to collect covert intelligence or military data. It is commonly referred to as Keyhole 8 or GAMBIT-3.

### Q: When did KH-8 Gambit 3 first fly and when was it retired?
A: The KH-8 family had its first flight on 1966-07-29 and was retired from service on 1984-08-13.

### Q: Who built and operated the KH-8 Gambit 3 satellites?
A: The United States Air Force operated the KH-8 series. Major contractors included Lockheed Corporation (Satellite Control Section), Kodak (Photographic Payload Section), and General Electric (Satellite Recovery Vehicle/space capsule).

## Why It Matters
KH-8 Gambit 3 represents a dedicated spacecraft model family within the United States’ reconnaissance satellite programs. As an organized series of photographic reconnaissance satellites, it combined specialized subsystems from multiple manufacturers: Lockheed for satellite control, Kodak for the photographic payload, and General Electric for the recovery vehicle. Operated by the United States Air Force, the KH-8 series fulfilled the specific operational role described by its parent class: covert collection of intelligence and military data from space. The program’s operational timeframe — from its first flight in 1966 to retirement in 1984 — places it as a sustained capability that spanned multiple years of service. Its design partitioning (control, payload, and recovery by distinct contractors) and use of a recovery vehicle for payload return are notable organizational and technical traits that defined its operational profile within the family of U.S. reconnaissance satellites.

## Notable For
- Being a dedicated family of U.S. reconnaissance spacecraft models (KH-8 / GAMBIT-3).
- First flight on 1966-07-29 and official retirement on 1984-08-13, marking an extended operational period.
- Subsystem manufacturing split: Lockheed (control), Kodak (photographic payload), General Electric (recovery vehicle/space capsule).
- Operated by the United States Air Force and designed for covert intelligence/military data collection.
