In 1970, Euryalus became the Gibraltar guard ship, a role that a number of Leanders performed.
In 1972, Euryalus undertook a Beira Patrol, designed to prevent oil reaching Rhodesia via Mozambique.
The following year, Euryalus began her modernisation at Devonport Dockyard, which included the removal of her twin 4.5-in gun to accommodate the Australian-designed Ikara anti-submarine warfare (ASW) missile system.
The modernisation was completed in 1976.

In 1977, the highlight of the year was the taking part in June of the Fleet Review of the Royal Navy, in celebration of HM the Queen's Silver Jubilee.
She was positioned in the middle of her sister-ships Scylla and Danae.

In 1978, Euryalus was a member of the 2nd Frigate Squadron (F2) more commonly known as the Portland Training Squadron, spending most of her time in and around Portland Naval base.
 She took part in various exercises, including the dreaded "Thursday War", helping to train warships and auxiliaries of the Royal and Foreign navies as part of maintaining their operational effectiveness.
 However it was not all work and no play as she carried out visits to Bayonne in France, Aalborg in Denmark, and a "Meet the Navy" visit to her adopted town of South Shields where she took part in the activities to commemorate the wartime exploits of HMS Kelly, the highlight of which was a visit by Earl Mountbatten of Burma.
