Air Attack
MissileAttack
ASuW Asymmetric Threat Massed attack by very small, fast, agile craft
- The Boghammer Threat Size: ~ 4sq m (frontal area) Speed: 40-60 Kts Threat: rocket attack/suicide
mission/terrorist/specialforces
Number: ~10 to 25
Issues Arising from BoghammerThreat
To prevent attack from enemyweapons - RPG/ATGW, etc.
Minimum Keep-Out-Range
Key Issues: Detection Defeat
Max. engagement range. Pk at range. Rate of Fire. Stowed on-mount ammunition. Time to Acquire & Slew.
Multiple target attack
