Valhalla's keel was laid on 8 August 1916 at the Cammell Laird Shipyard in Birkenhead.

She was propelled by three Yarrow-type water tube boilers powering Parsons geared steam turbines developing 27,000 shaft horsepower (20,000 kW) and driving two screws for a maximum designed speed of 34 knots.

[1] She was armed with 4 QF 4-inch (101.6 mm) Mk V L/45 guns in four single centre-line turrets.

Aft of the 3-inch gun, she carried four 21-inch torpedo tubes mounted in pairs on the centre line.
