Point defence (or point defense; see spelling differences) is the defence of a single object or a limited area, e.g. a ship, building or an airfield, now usually against air attacks and guided missiles. Point defence weapons have a smaller range in contrast to area-defence systems and are placed near or on the object to be protected.
Point defence may include:
- short-ranged interceptor aircraft
- Close-in weapon systems on ship
- land-based short-ranged anti-aircraft guns or surface-to-air missile systems
- Active protection systems on tanks or other armoured fighting vehicles
Coastal artillery to protect harbours is similar conceptually, but is generally not classified as point defence. Similarly, passive systems—electronic countermeasures, decoys, chaff, flares, barrage balloons—are not considered point defence.
