KG-40 was a half-duplex cryptographic device that provided data protection for the US Navy 's Link 11 system and other systems that met the Tactical Data Information Link A (TADIL-A) data standards. It was developed in the US in the mid-1970s and was used by the US Department of Defence (DoD) and by NATO.

The KG-40A is a mandatory modified version of the older KG-40, which incorporates variable fill capability. The modification entails replacement of a printed circuit board (motherboard) and the front panel assembly.

The KG-40AR is a functional and physical drop-in replacement for the (now obsolete) KG40 and KG-40A COMSEC devices, developed and produced by Ultra Electronics Ltd. in the UK around 2004, for the US Department of Defence (DoD) and NATO.
