## Summary
SAMOS is an American series of reconnaissance satellites operated by the United States Air Force. The program (also called Satellite and Missile Observation System or SAMOS-E) produced multiple satellites including SAMOS 1, SAMOS 2, and SAMOS 3; at least two early vehicles (SAMOS 1 and SAMOS 3) were lost in launch failures.

## Key Facts
- SAMOS is a United States reconnaissance satellite series operated by the United States Air Force.
- Official aliases include "Satellite and Missile Observation System", "SAMOS-E", and the Japanese name "セイモス計画".
- SAMOS is recorded as an instance of a spacecraft series and a satellite program, and is subclassed as a reconnaissance satellite (a satellite that covertly collects data for intelligence or military applications).
- Named program vehicles include SAMOS 1 (destroyed in a launch failure), SAMOS 2 (American reconnaissance satellite), and SAMOS 3 (lost in a launch failure).

## FAQs
### Q: What is SAMOS?
A: SAMOS is a United States Air Force-operated series of reconnaissance satellites, known formally as the Satellite and Missile Observation System (SAMOS-E). It is classified as a spacecraft series and satellite program for covert intelligence or military data collection.

### Q: Who operated the SAMOS satellites?
A: The SAMOS satellites were operated by the United States Air Force.

### Q: What happened to SAMOS 1 and SAMOS 3?
A: According to available records, SAMOS 1 was destroyed in a launch failure and SAMOS 3 was lost in a launch failure.

## Why It Matters
SAMOS matters because it is part of the class of spacecraft—reconnaissance satellites—designed to collect intelligence or military data from space. As an American, Air Force-operated satellite program, SAMOS represents a governmental effort to field spaceborne observation platforms under the designation "Satellite and Missile Observation System." Programs of this type provide platforms for covert observation, surveillance, and collection of strategic information that support national security and defense decision-making. Even the program’s failures (for example, SAMOS 1 and SAMOS 3 being lost in launch mishaps) are relevant: they illustrate technical and operational risks inherent in deploying reconnaissance assets to orbit and inform later program planning, risk assessment, and satellite program management. The existence of SAMOS in public records, multiple language Wikipedia entries, and dedicated media (Commons) underscores its role as a documented element of U.S. spaceborne reconnaissance efforts.
