The Eagle Mk.3 is a versatile small interceptor. The Eagles in the AJN fleet are deployed as escorts, small fighters, carrier-bound ships and advanced combat trainers.

A small number of Eagles are used as advanced combat manoevering trainers; most of the fleet is on active duty as interceptors/escorts for transports and ground assault craft. A small number has been made "stealthy" by redesigning certain parts of the hull to make detection harder - these ships are employed to perform intelligence missions into hostile territory.
The current variants are:
