All this required the involvement of large resources, the lack of which was the reason that their implementation was delayed. The reconstruction of the Arkhangelsk-Vologda railway ended in January 1916, and the construction of the Murmansk road was completed in 1917. Observation posts were set up in the throat of the White Sea, and a battery of 4-47-mm guns was installed on Mudyug Island.
Already at the end of 1914, the enemy began to lay mines, and at the beginning of the navigation of 1915, the German command sent an auxiliary cruiser, Meteor, into the throat of the White Sea - he put 285 mines. A number of merchant ships died on the mines and the British auxiliary cruiser Arlanz was blown up. Since June 1915, the defense of the Arkhangelsk port and the protection of maritime communications in the theater of operations have become more organized and effective.
In July 1916, an order to form flotilla Of the Arctic Ocean. The flotilla was supposed to include a cruising detachment, a trawling division, defense units of the Kola Bay, Arkhangelsk port, as well as a communications and surveillance service. The main tasks of the flotilla are: escorting ships in mine-hazardous areas, security, sentinel service, coastal defense.
In 1916, the construction of a base began in the depths of the Kola Bay - near the Semenovye Islands. A trade port was built in the Kola Bay near the village of Romanov (the future Murmansk).
The German command, assessing the importance of the northern maritime communications that linked Russia with its allies on the Entente and neutral states, sent submarines in the second half of 1916 for active operations in this theater. In August and September, German submarine minzagi installed 72 mines at the entrance to the throat of the White Sea - several ships were killed. Since September, 1916, enemy submarines began to appear on the outskirts of the Kola Bay.
The Russian command took measures on anti-submarine defense, reducing the losses to a minimum by October.
In the 1917, in the composition of the fleet of the Arctic including: Battleship ( "Chesma"), 2 cruiser ( "Varyag" and "Askold"), 4 destroyers, destroyer 2, 3 submarine minelayer, 40-trawlers and trawlers boats 2 icebreaker and up to 20 auxiliary ships.

1. "Chesma".
In the North Sea Theater, the enemy lost 3 submarines: U 56 (sunk by the destroyer Thunderstorm), U 76 (destroyed by minesweepers) and U 28 (killed by an explosion of attacked vehicles with military cargo).
2. U-28 in 1915 from the seized vessel.
The young fleet declared itself in full voice.
In 1917 on the Black Sea, the fleet continued fighting on enemy communications, making it difficult to deliver weapons and food of the Turkish army on the Caucasian front, shelling coastal objects, blocked the Bosphorus.
The main event for the Baltic Fleet weakened by the revolution in 1917 was the participation in the Moonsund operation.
