Peacetime practice involved the dropping of small practice bombs on instrumented bombing ranges, and a system of predicted bombing using radio tones to mark the position of the bomb drop over non-range targets, the bomb error being calculated by a ground radar unit and passed either to the crew during flight or to a headquarters for analysis.
Use of the Valiant's Navigational and Bombing System (NBS) and the high quality of assigned crews, who were typically veterans and often had been previously decorated for wartime service, meant a high level of bombing accuracy could be achieved, greater than that of aircraft during the Second World War.
According to Gunston and Gilchrist, Valiant crews were able to place practice bombs from an altitude of 45,000 feet (14,000 m) within a few meters of their assigned target.

In October and November 1956 the Valiant was the first of the V-bombers to see combat, during the Anglo-French-Israeli Suez campaign.
During Operation Musketeer, the British military operation in what became known as the Suez Crisis, Valiants operating from the airfield at Luqa on Malta dropped conventional bombs on targets inside Egypt.
Egyptian military airfields were the principal target; other targets included communications such as radio stations and transport hubs.
On the first night of the operation, six Valiants were dispatched to bomb Cairo West Air Base (which was aborted in flight due to potential risk to US personnel in the vicinity) while six more attacked Almaza Air Base and a further five bombed Kibrit Air Base and Huckstep Barracks.

Although the Egyptians did not oppose the attacks and there were no Valiant combat losses, the results of the raids were reported as disappointing.
Although the Valiants dropped a total of 842 long tons (856 t) of bombs, only three of the seven airfields attacked were seriously damaged.
The Egyptian Air Force had been effectively destroyed in a wider series of multinational attacks of which the Valiant bombing missions had been a part.
It was the last time RAF V-bombers flew a live combat mission until Avro Vulcans bombed Port Stanley airfield in the Falkland Islands during the Falklands War in 1982.
