Gun models included both older fixed carriage guns and more modern weapons with counter-recoil systems. Krepost Sveaborg had both a regular telephone system and a second, independent telephone network dedicated for fire control. [12], 6 in (152 mm) 45 caliber model 1892 Canet gun, 11 inch and 9 inch model 1877 coastal mortars, 75 mm (3 in) 50 caliber model 1892 Canet gun, Field guns were used on both the land front and as anti-landing and close defence weapons on the coastal forts. We bridge the gulf between the Australian business media and reality. The batteries were located on Rysäkari, Katajaluoto, Kuivasaari, Isosaari (two batteries) and Itä-Villinki. Heavily fortified caponiers providing flanking fire were built on places of the front line. Additionally the island had 2-4 antiaircraft guns of 75 mm or 3 in (76 mm) during the war. Unless you had anticipated the approval, the big problem with getting the GFC 500 installed is finding an installer who can do the job before the end of the year---at any price. Kuivasaari telephone exchange was also the central gunnery telephone exchange. In summer 1916 the 75 mm anti-aircraft battery on Melkki was relocated to Itäinen Pihlajasaari 60°8′23.03″N 24°55′20.02″E / 60.1397306°N 24.9222278°E / 60.1397306; 24.9222278. Welcome to our website.
Asian workers were transported back to Russia already in 1917 however, citing the workers to be unaccustomed to the northern climate and possible threat of rebellion.

The 76 mm model 1902 gun was also used as an anti-aircraft gun on a modified "Rosenberg" mount. The payment for fortification works was slightly above average for manual labour, and made it an attractive option particularly for many rural workers.

The northern shore of the island has a heavily fortified concrete bunker used as mine control bunker, telephone exchange and electrical station. Thus when the fleet attacked the fortress on the 6th of August 1855 they were able to bombard the fortress for two days from a distance of 4–5 km (2.5–3.1 mi) while the best Russian guns had a maximum range of 2,500 m (8,200 ft).

Target indication between the primary and secondary points could also pose problems, as there would often be several similar target ships. We may change this policy from time to time by updating this page. We may collect the following information: What we do with the information we gather. During the First World War the only battery was a land front battery number 116 at Vaskiniemi, armed with four 9 in (229 mm) model 1867 guns in March 1915.

Kyrgyz were mainly guards. The main line of defence had the newest fortifications and the heaviest and most modern armament. Target information was sent from the primary point to the battery command point. 76 mm model 1902 gun was a newer rapid fire field gun with a counter recoil system. [1]:23–24, Melkki 60°7′54.65″N 24°53′17.97″E / 60.1318472°N 24.8883250°E / 60.1318472; 24.8883250 is located south of Lauttasaari. Lauttasaari, Meilahti and Laajasalo were also fortified to some extent.

[1]:23–24, At the start of the war the fortification artillery units manning the fortress were organized into nine artillery companies and a machine gun detachment.

The construction of the battery began in October 1914 and the guns were placed on their foundations in early 1915 with the parapet and traversal walls completed in autumn 1915. The island's central location and size made it the most heavily armed coastal fort and it was part of the plans for expanding Krepost Sveaborg already in 1909. The main fire control station of the fortress with the only 6 m (20 ft) rangefinder was located in Kuivasaari. Most of the older guns, including eleven 6 inch 190 pood siege guns and thirteen 9 inch coastal mortars, were transported to the land front of the fortress shortly after the start of war. [1]:60–62, Kuivasaari island 60°6′3.49″N 25°0′54.97″E / 60.1009694°N 25.0152694°E / 60.1009694; 25.0152694 is located west of Isosaari. The heavy shells of the mortars were considered to have a "suitable moral effect" (Finnish: asianmukaisen moraalisen vaikutuksen)[1]:33 on civilians. The minefields around the fortress were built by the Krepost Sveaborg mine company, from 1915 a mine battalion.

[1]:55–57, Katajaluoto island 60°6′0.57″N 24°54′54.68″E / 60.1001583°N 24.9151889°E / 60.1001583; 24.9151889 is a narrow, north–south oriented island located approximately half way on the line between Rysäkari and Harmaja.
A total of 32 new bomb-proof stone powder cellars were built by the beginning of the 1870s, further improving the defences. A six-gun battery of 6 inch model 1877 siege guns on fortress carriages were transported to the land front by the end of 1914. Shelter for crew and ammunition cellars were built into and under the front parapet and the traversal walls. Subscribe to our newsletter and we'll keep you up to date on our products and services.

Fortification works continued until the February revolution of 1917, and some work was done until early 1918. The average distance between the two points at Krepost Sveaborg was 5.5 km (3 mi). The most common models were the 6 inch siege gun model 1877 with a 190 pood version used on both field and fortress mounts and a lighter 120 pood barrel version on field carriage.

From the late 19th century until the First World War Vallisaari was the most heavily fortified island of the fortress. Fortified electrical stations provided the necessary electricity for the mine control network. We use traffic log cookies to identify which pages are being used. During the war new fortifications were built on the outlying islands pushing the defences outward to protect the ships in the harbour from new modern guns. The web application can tailor its operations to your needs, likes and dislikes by gathering and remembering information about your preferences.

There is also a unique fortified concrete latrine on the eastern shore. Four companies manned the coastal forts at sea front. The guns were on temporary wooden platforms, and the battery was relocated already in August as construction of new fortified concrete anti-aircraft positions and shelters began.
