, which was still close to its southern winter limit.
The sun remained above the horizon at this time of year and the deck crews of the ships found the perpetual daylight fatiguing and stressful; glare from sunshine reflecting off ice being particularly difficult for observers. On 25 May air attacks began, the German bombers and torpedo-bombers co-ordinating their attacks. Torpedo-bombers launched at the same time to make it harder for ships to evade the torpedoes. The air attacks continued until 1 June and sank six ships, one other being lost to a U-boat; 3–6 German aircraft were shot down and one damaged; on 27 May, 108 attacks by aircraft had been counted.
After the convoy, the escort commander recommended that convoys be given far more anti-aircraft fire-power and air cover from an

, began on 22 June 1941, the UK and USSR signed an agreement in July that they would "render each other assistance and support of all kinds in the present war against Hitlerite Germany". Before September 1941 the British had dispatched 450 aircraft, of rubber, 3,000,000 pairs of boots and stocks of tin, aluminium, jute, lead and wool. In September British and US representatives travelled to Moscow to study Soviet requirements and their ability to meet them. The representatives of the three countries drew up a protocol in October 1941 to last until June 1942 and to agree new protocols to operate from 1 July to 30 June of each following year until the end of Lend-Lease. The protocol listed supplies, monthly rates of delivery and totals for the period.
The first protocol specified the supplies to be sent but not the ships to move them. The USSR turned out to lack the ships and escorts and the British and Americans, who had made a commitment to "help with the delivery", undertook to deliver the supplies for want of an alternative. The main Soviet need in 1941 was military equipment to replace losses because, at the time of the negotiations, two large aircraft factories were being moved east from Leningrad and two more from Ukraine. It would take at least eight months to resume production, until when, aircraft output would fall from 80 to 30 aircraft per day. Britain and the US undertook to send 400 aircraft a month, at a ratio of three bombers to one fighter (later reversed), 500 tanks a month and 300
Bren gun carriers. The Anglo-Americans also undertook to send of aluminium and 3, 862 machine tools, along with sundry raw materials food and medical supplies.

expanding southwards, the convoy route ran closer to Norway. Until early March 1942 one merchant ship of the 110 sent via the Arctic route had been lost; the condition of the receiving ports in the USSR caused more difficulty than German anti-convoy operations by ships, submarines and aircraft. As the summer season approached the hours of daylight increased just as the size of convoys got bigger to alleviate the accumulation of ships awaiting dispatch.
