The Wallace-class guided missile destroyer marked a policy change in the Royal Isselmere-Nieland Navy. No longer would the Royal Navy operate specialised air defence and anti-submarine destroyer designs, but would use a single general purpose design capable of performing both tasks adequately.
The destroyer is a definite progression from the previous classes, the County-class air defence destroyer and City-class anti-submarine destroyer. The Wallace-class is designed to operate two Cormorant HM.1 maritime patrol helicopters and sports both heavy surface-to-air missile and good anti-submarine armaments consisting of the GWS.41 Loon anti-submarine missile and the GWS.63 Barracuda lightweight torpedo.
The MRU.113 active electronically scanned array radar, consisting of four receive/transmitter (transceiver) module panels a complete 360° arc around the vessel, is equipped with ground and marine moving target indicator technology (GMTI/MMTI) capable of picking out targets with a small radar cross-section operating at low-level over sea at a good distance, or to discern moving targets on land for naval fire support missions. The radar serves to search, identify and track targets for prosecution, assisted by the MRS.118 3-D air volume search and the MRS.164 surface search radars.
Against submarines and other underwater targets, the Wallace-class not only has two anti-submarine helicopters, but also an MQU.134 keel-mounted dual mode (i.e. active or passive) low frequency sonar and an MQR.146 passive towed array that connects the MQS.145 dual mode variable depth sonar (VDS) fish to the ship. In active mode, the sonar is able to produce synthetic apertures allowing the Wallace-class to assist in mine countermeasures operations.
The class is capable of serving as a command platform for destroyer-escort groups, a capacity that it performed throughout its operational service.
Although the Wallace-class no longer serves as a destroyer in the Royal Navy, there are plans to re-introduce modernised units as frigates to replace the hard-worked Bullfinch-class.
