Prototype Wildcat T1 No.3 features an under nose radome. It will initially undertake communication systems testing and navigational work, before moving on to gather data for structural integrity tests.

T1 No.2, ZZ401, flew for the first time on October 14, 2010. It is the primary electrical and avionics test bed for systems including DAS and EODS. Wiring fitted to the side of the aircraft is for test instrumentation.

T1 No.1 ZZ400 is primarily used to undertake trials confirming the aircraft's initial flight envelope. Here it is equipped with string markers to aid visualisation of airflow around the airframe. It will soon leave for the US to undertake hot-and-high testing in Colorado.

Upturned exhausts on the CTS800-4N engines deliver hot efflux into the rotor disc, where it is dissipated for a decrease in the helicopter's IR signature.

The first production vehicle, ZZ398, undertakes its first flight test in late April 2011. It bears 'Army' titles and the colour scheme that will be similar for both the AH and HMA variants.

In this April 2010 photograph, T1 No.1 looks very different without the now familiar tailplane.

Wildcat's cockpit features four large multi-function colour displays.
