The Type 11 Surface-to-Air Missile (11式短距離地対空誘導弾) or Tan-SAM Kai II is a Japanese developed surface-to-air missile currently in service with the Japan Self-Defense Forces.

The system was developed by Toshiba as a further improvement of the Type 81 Surface-to-Air Missile.

Development work on Tan-SAM Kai II started in 2005 and in 2014 Type 11 missile was officially unveiled.

The AESA radar and fire control system is carried on an Isuzu Type 73 6×6 truck.

In JGSDF service the four-tube missile launcher is also carried on a separate Type 73 truck, while in JASDF service a Toyota Mega Cruiser 4×4 is used instead.
