Subspace amplifier

A subspace amplifier was a communications array designed to allow real-time subspace communication.

A series of subspace amplifiers were deployed by the Earth starship Enterprise during its initial exploratory mission. The amplifiers were deployed to allow better communication with Earth and United Earth Starfleet Command. The amplifiers were designation by letter-number combinations. The first such device, Echo One, was deployed in July of 2151, with Echo Two being deployed two months later. 

In September of 2151, an alien vessel destroyed both Echo One and Two during a sustained attack on Enterprise. Following the successful elimination of the alien threat, a third amplifier was dropped, to replace the lost two.
