Two pairs of the boats were ordered in May 1963 from Vickers Shipbuilding Ltd, Barrow in Furness and from Cammell Laird and Co. Ltd, Birkenhead.
The option of buying a fifth unit, planned as Ramillies,  was cancelled in February 1965 as a cost-savings measure by the government of Prime Minister Harold Wilson.
Traditional battleship names were used, signifying that they were the capital ships of their time.

Vickers Armstrong in Barrow-in-Furness constructed Resolution and Repulse and Cammell Laird in Birkenhead constructed Renown and Revenge.
The construction was unusual in that the bow and stern were constructed separately before being assembled together with the American-designed missile compartment.

The design was a modification of the Valiant-class fleet submarine, but greatly extended to incorporate the missile compartment between the fin and the nuclear reactor.
The length was 130 metres (430 ft), breadth 10.1 metres (33 ft), height 9 metres (30 ft) and the displacement 8,400 long tons (8,500 t) submerged and 7,600 long tons (7,700 t) surfaced.
A Rolls-Royce pressurised water reactor (PWR1) and English Electric Company turbines gave them a speed of 25 knots (46 km/h) and they could dive to depths of 275 metres (902 ft).
Sixteen Polaris A3 missiles were carried, in two rows of eight.
For emergencies there was a diesel generator and six 533-millimetre (21 in) torpedo tubes located at the bow, firing the Tigerfish wire-guided homing torpedoes.
The submarines put to sea with a crew of 143.

According to former head of the Royal Corps of Naval Constructors R.J. Daniel, the Resolution-class SSBNs possessed five features that were envied by the United States Navy: the machinery loading hatch, automated hovering system, welded hull valves, standardised valves, and raft-mounted propulsion machinery.
