At the very beginning of the Continuation War the 7th Coastal Brigade took up positions in the Åland Islands. The only significant event at the beginning of the Continuation War was the Battle of Bengtskär (26.-27.7.1941), where a force from the Soviet Union naval base in Hanko attempted to invade the island of Bengtskär. The coastal batteries of Örö supported the Finnish defenders, and a counter-attack force from the men from Örö and Hiittinen repelled the invaders. Otherwise the action in the area was limited to Soviet air activity. The 5th Coastal Brigade was transferred to East Karelia and reformed as the Lake Onega Coastal Brigade. 7th Coastal Brigade was thus the only unit remaining in the Archipelago Sea area, and it became the Archipelago Sea Coastal Brigade ("Saaristomeren Rannikkoprikaati")) on 1.3.1942. Hiittinen Sector, formerly part of the Hanko Group, became also part of the brigade. The brigade was reorganized on 29.4 as two coastal artillery regiments, the 7th on Archipelage Sea and the 17th on Åland Islands, plus Bothnian Sea coastal guard and units directly subordinated to brigade headquarters. With the Soviet Baltic Fleet trapped at the eastern end of the Gulf of Finland the threat for the brigade was low and the regiment headquarters were not established and only the most important forts were manned. During the Soviet Vyborg–Petrozavodsk Offensive in 1944 units from Åland Islands and Archipelago Sea were transferred east to reinforce the defences there. To fulfill the ranks older men already released from service were recalled. After the Soviet offensive was halted on late summer of 1944 the defence of Åland Islands was reinforced to guard against a possible German invasion. While there were no clashes between Finnish and German forces in Åland Islands or Archipelago Sea area, a force of three German ships that had left Finland late were allowed to pass by the Utö fort on 19.9.1944, the same day that Moscow Armistice was signed. The German heavy cruiser Prinz Eugen along with escorts was patrolling of Utö, coming to a range of at closest, when the three ships sailed by. Utö fort was at battle stations during the event, and guns on the three German ships were similarly manned. After Continuation War Åland Islands were again demilitarized and the fortifications built there demolished.
