The combined naval strength of Sweden and Finland

Earlier this week both Sweden and Finland agreed to cooperate together on a military level. Central in this cooperation is the creation of a joint naval task force and mutual access to each other’s naval bases. Aside from the Russian navy, the Swedish navy is already the most powerful in the Baltic Sea and yet, by teaming up with the Finnish navy it would further strengthen the Swedish navy as well as the Finnish.

 

The Baltic Defence blog made a more detailed overview of how the strength of both the Swedish and Finnish navies will evolve in the next decade as well as a discription of the strategic and tactical implications of this joint naval cooperation.

Overview of the Baltic States navies

General overview

The Baltic states compose of 3 small countries: Estonia, Latvia and Lithuania. These countries have small economies and can economically not afford a large standing navy, especially when the armed forces of these countries are all focused on the army and how to deter Russia.

All three countries have a focus on mine countermeasure (MCM) warfare. As a part this task has been historically since the Baltic Sea is covered with sea mines from both World Wars and the Cold War. In a more modern approach MCM has the current relevance in keeping the Baltic ports open for both trade as well as an economic window with the western world. The ports also serve as points of debarkation for EU and NATO forces in case of any crisis.

Only Lithuania and Latvia have the capability to patrol their coastal waters with special patrol boats. Both countries operate modular ships in an attempt to increase their operational capabilities.

In general it is clear that the Baltic navies can keep their own waters free of mines but when it comes to powerfully enforcing their own sovereignity in their coastal waters and Exclusive Economic Zone (EEZ) then these countries require the aid and protection of frigates and destroyers, supplied by other EU navies.

Estonia

The Estonian navy is mainly focused on minesweeping and mine hunting. Since the Baltic Sea is covered with sea mines from both World Wars and the Cold War this is not a surprise. At the same time the port of Tallinn is the only major port in Estonia and both the port as its approaches can be blocked by sea mines.

The Estonian Navy has therefore in the past 10 years made a strong contribution to the Standing NATO Mine Countermeasure Groups (SNMCMG). It has also taken part in several operations aimed to integrate the maritime forces in the Baltic Region as well as cooperation with other EU and NATO partners. These operations include BALTOPS, Open Spirit and Northern Coasts.

The Estonian navy only operates 5 different ships. The main units are the 3 minehunters of the British Sandown class. These ships were laid down in 1988, 1990 and 1992 and transferred to the Estonian Navy between 2006-2009. Although these ships are 26 to 20 years old they still have an expected life service for another 10 to 15 years, depending on the wear and tear and quality of the maintenance. Still, around the 2025 timeframe the Estonian navy will be forced to start looking for replacements.

Also in service with the Estonian navy are the two Danish build diving ships that are part of the mineships division of the Estonian Navy. These two ships of the Lindormen class are built in 1977 and transferred in 2006 and 2009 to the Estonian Navy. One of these ships is currently in reserve. The author didn’t managed to get any details about these two ships but these ships,  given their age of 37 years, are also in need of replacement in the next coming years.

Latvia

Just like Estonia, Latvia has a focus on mine countermeasure warfare although it also operates a small contingent of (coastal) patrol boats. Unlike the Estonian navy sole focus on MCM operations, the Latvian navy is tasked with blocking harbors and shipping routes in case of crisis as well as providing control, surveillance and intelligence of inner and territorial waters and the economic zone, and providing Coast Guard functions.

The major units in the Latvian navy are the 5 tripartite minehunters it received from the Dutch Navy in the 2007-2011 timeframe. These are the same class of minehunters that are also in use by the Dutch, Belgian and French navy. Build in 1984, these vessels are currently 30 years old. Given the fact that both the Dutch as the Belgian navy are planning to replace these vessels in their own navies around the 2020 timeframe then one can expect that Latvia will follow this move and start looking for new minehunters around the 2020-2025 timeframe.

The 5 patrol boats of the Skrunda class form the other major part of the Latvian navy. These ships are aimed to patrol the coastal waters and enforce Latvian law such as fisheries inspections, search and rescue, sovereignty enforcement and other tasks.  Build between 2009 and 2013 these are the most modern ships in the Latvian navy. These ships are also capable to carry a mission module the size of a 20ft ISO container and a weight up to 6 tons. This allows each ship to carry a mission module tailor made for each type of mission ranging up from weapon systems, hydrographic survey or even supporting equipment for divers.

The Virsaitis  class minelayer dates back from 1978 and was transferred from Norway to the Latvian navy in 2003. The ship currently serves as the command and support vessel although it is still capable of performing the task of lying mines.

The Varonis dates back from 1973 and entered service in 2004 after having served in the Dutch navy and serves now as a logistics and training vessel.

Lithuania

The main element of the Lithuanian navy are the 3 ships of the Danish Flyvefisken class patrol vessels, also known as the Standard Flex  300 class. These ships were transferred to the Lithuanian navy in the 2008-2010 timeframe. Although these ships are built between 1985 and 1995 they are still in a good condition. The main advantage of the Standard Flex  300 is that it is capable of carrying mission modules in containers, allowing these ships to change their roles in a 48 hour timeframe. These ships can either be used for surveillance and combat against light enemy warships or to perform MCM or minelaying operations. They even have the capability to carry Harpoon missiles and light weight torpedo’s.

Like it’s two Baltic neighbors, the Lithuanian navy also has a MCM capacity that is currently in the process of being upgraded. The two Lindau class minesweepers dating back from 1957 are replaced by two Hunt class minehunters from the Royal Navy. However, these two ships will be in need of replacement in the 2020-2025 timeframe given the fact that they date back from 1982 and are already 32 years old. Nevertheless is the transition from minesweeping to minehunting already a big improvement for the Lithuanian navy. Before these two minehunters were delivered they underwent upgrades both in sonar, weapons as machinery.

Overview of the Swedish Navy

The Swedish Navy is one of the biggest navies in the Baltic Sea together with the Russian Baltic Fleet. These two countries alone have more naval power then their neighbors and as such they determine the balance of power in the Baltic Sea.

The Swedish armed forces face themselves in a strange situation. On one side they are not a NATO member but on the other hand they are a part of the European Union (EU) of whom most member states are NATO members. This complicated situation means that in case of war involving NATO, Sweden would be neutral but any war involving the EU would mean Sweden does have to be involved as well. This makes defense politicians wonder in what kind of scenario’s Sweden would be involved in which ones they would remain neutral.

Thus Sweden poses a great unknown in the Baltic Sea. It is therefore important to understand the strength of the Swedish Navy in order to understand what military force Sweden can decide to deploy inside the Baltic Sea and beyond.

Submarines

The Swedish Navy has in its inventory a decent arsenal of diesel-electric submarines.

The oldest submarines in the Swedish navy are the 2 Södermanland class submarines (or the A-17 class) . Originally constructed in 1988, these submarines underwent a major modernization program in 2003-2004 with the installation of air-independent propulsion (AIP), allowing these submarines to stay under water for several weeks. Also during these modernizations there was an update on their filter systems and cooling units. These are now converted to operate optimally with cooler, less saline water. As such, these submarines are well suited to operate in the northern Atlantic Ocean or Baltic Sea, meaning their mean adversary would be the Russian Navy. These 2 submarines are planned to be retired around 2019-2020 and will be replaced by a new class of submarines.

The 3 submarines of the Gotland class (A-19) are the backbone of the Swedish submarines. Commissioned in 1996, these submarines operate with AIP. Their engines can use the surrounding sea water as a heat sink, therefore diminishing the need for cooling pumps, generally believed to be the loudest piece of equipment on board of a submarine. A high degree of automation on these submarines allow them to operate with a minimum crew. In retrospect, a diminished crew allowed to build better living spaces on board which in turn improves the overall endurance of the crew.

The Gotland class operates two type of weapons. The four 533mm torpedo tubes are used to fire anti-ship torpedo’s. These torpedo’s are wire guided and can be steered on their target from the submarine. The two smaller 400mm torpedo tubes are used to fire anti-submarine torpedo’s.

All 3 Gotland class submarines are planned to be overhauled to increase their life span to 2025. The overhaul is currently ongoing and is expected to end in 2017.

Two new A-26 class submarines are currently being constructed in order to replace the two older Södermanland class submarines.

Corvettes

Given the nature of the Swedish coastline, small corvettes are more suited to defend the littoral waters and protect the Swedish sovereignty. Sweden can rely on a small but modern and well equipped force of corvettes to protect its shores.

Commissioned in 1986, the two Stockholm class corvettes are the oldest corvettes in the Swedish Navy. These two corvettes were rebuild and modernized in the 1999-2002 period and are capable of serving in the Swedish Navy until halfway the 2010’s. Armed with anti-ship missiles and a 57mm gun these ships are designed for anti-surface warfare.

Just like the Stockholm class, the last two remaining Götenborg class corvettes are designed for littoral combat and anti-surface warfare. Commissioned in 1990 and 1993 these ships are going through a mid-life modernization to extend their service life to the mid 2020’s.

The by far most renowned corvettes in the Swedish surface fleet are the Visby class corvettes. These five stealth corvettes are Swedish most modern vessels. The main role of these ships are mine countermeasures (MCM) and anti-submarine warfare. This emphasizes Sweden’s view on its Baltic position in which many mines can still be founds and many nations have quite submarines, as lately has been proven by what was thought to be a Russian midget submarine operating in Swedish territorial waters.

For the anti-surface warfare capabilities the Visby class relies on anti-ship missiles and a 57mm gun. The ship can also deploy 400mm torpedo’s, depth charges and rocket-powered grenade launchers to perform an anti-submarine warfare role. The Visby class is also capable of letting helicopters land, refuel and take off from its deck but lacks a hangar to store a helicopter.

In the future the Swedish Navy plans to replace their two Götenborg class corvettes with two K-40 class corvettes. The K-40 is envisioned to be an enlarged Visby class corvette up to a frigate size. The commissioning of these two vessels is planned in the mid 2020’s.

Other ships

The Swedish Navy can, aside from the previous mentioned main naval forces, count on several other vessels. 12 Trapper class coastal patrol boats with machineguns as well anti-submarine rockets, depth charges and mines add another force capable of defending and patrolling the Swedish coast. Adding to this capacity are up to 147 CB90 combat patrol boats and although these belong to the Swedish Naval Brigade, they can be used to patrol the coast as well.

Sweden can also count on 5 minehunters from the Koster class to deal with any mine treath. The most important support ships are the Orion that can collect intelligence and the Belos that is being used as submarine rescue ship.

Conclusion

The Swedish Navy operates two distinct navies. It’s green water navy with diesel-electric submarines and modern corvettes are all aimed to operate in the Baltic Sea. It’s brown water navy of patrol boats  are used for coastal defense as well as patrols in the littoral.

Sweden is a neutral country, and it has the tools to enforce its neutrality. However at the same time Sweden is carefully looking towards the Russian Baltic Fleet. As Sweden and Russia have always been at odds with each other it is naturally that Sweden views the Russians as their main opponent. As such, Sweden will always try to match the Russian combat power in the Baltic Sea both in numbers as well as in quality.
