PRR is only partially connected with the Bowman programme, insofar as it was hived off from the acquisition process in October 1999 for more rapid implementation, and the first of 45,000 units formally entered service in early 2002. Operating in the 2.4 GHz band, PRR has no integrated encryption devices and does not intercommunicate with the rest of the Bowman network, but is widely acclaimed as having revolutionised intra-squad communications and small-unit tactics.

Models are designated "UK/PRC", which stands for "United Kingdom / Portable Radio Communications", or "UK/VRC", which is "United Kingdom / Vehicle Radio Communications". Following this logic "UK/ARC" stands for "United Kingdom / Airborne Radio Communications".

The manpack version of the ADR+ has an Automatic Situational Awareness Module inserted in BCIP 5.2 which enables Own Station Position Reports to be broadcast without the presence of an associated computer.

Under the terms of the baseline contract ITT Defence delivered some 26,000 ADR+ radios and 8,000 VPTs, complemented by 580 examples of the UK/ARC341 VHF aircraft role radio (a derivative of the company's SINCGARS AN/ARC-201D airborne transceiver) for helicopter platforms.
