Destruction of the Allied convoys was thus a top priority for the German Navy — and brought World War II to Novaya Zemlya. The most ill-fated and one of the largest Arctic convoys, code-named “PQ-17,” left Iceland on June 27, 1942. It consisted of thirty-four merchant ships, six destroyer escorts, fifteen additional armed ships (among which were two Free-French corvettes), and three small rescue craft. The fast-moving convoy encountered ice floes on June 30 and was forced to reduce speed. On the following morning, the convoy was

The largest underground test in Novaya Zemlya took place on September 12, 1973, involving four nuclear devices of 4.2 megatons total yield. Although far smaller in blast power than the Tsar Bomba and other atmospheric tests, the confinement of the blasts underground led to pressures rivaling natural earthquakes. In the case of the September 12, 1973, test, a seismic magnitude of 6.97 on the Richter Scale was reached, setting off an 80 million ton
