According to official press release from SAAB; Swedish Navy Gotland Class Submarine has been relaunched and is ready to start her sea trials after a comprehensive mid-life upgrade (MLU).
Due to this MLU, the Gotland submarine has capabilities that will be found in the next generation of Swedish submarines, the A26.
The Gotland was designed and built by Kockums in Malmö in the early 1990’s and commissioned in 1996. The mid-life modification consists of upgrades of onboard systems and technology, sustaining the submarine’s operability, and ensuring service to Sweden beyond 2025.
This updated version of the Gotland will pave the way for the most modern AIP submarine under production today: the A26 for the Royal Swedish Navy. More than 20 systems on-board the new Gotland-class will be implemented in the A26. The MLU of Gotland therefore contributes to the test and qualification of some of the innovative solutions to be implemented in the future Swedish A26 submarine class.
The relaunch ceremony of the Gotland took place in Karlskrona on June 20.

The Japan Maritime Self-Defense Force (JMSDF) commissioned its ninth Soryu-class diesel-electric attack submarine (SSK). JS Seiryū with a pennant number SS-509, was delivered to Japanese Navy with ceremony held in the Hyōgo Prefecture of Kansai, Honshu on March 12.
The 10th of the class, Shoryu (with pennant number SS 510), was launched in November 2017 by Kawasaki Heavy Industries (KHI), which has built four more boats of the class, and is expected to be commissioned March 2019. The JMSDF plans to operate a total of 12 such boats by March 2021.
The Soryu Class diesel-electric submarines are being built by Mitsubishi Heavy Industries and Kawasaki Shipbuilding Corporation for the Japan Maritime Self-Defense Force (JMSDF). Soryu Class is an improved version of the Oyashio Class submarine.
The submarine has an overall length of 84m, beam of 9.1m and depth of 10.3m. The normal draft of the sub is 8.4m. It has a surfaced displacement of 2,950t and submerged displacement of 4,200t. The Soryu Class can complement a crew of 65 including nine officers and 56 enlisted members. The submarine can sail at a surfaced speed of 13kt and submerged speed of 20kt. It has a maximum range of 6,100nm at 6.5kt speed.
Soryu is powered by a diesel-electric propulsion system. Two Kawasaki 12V 25/25 SB-type diesel engines and four Kawasaki Kockums V4-275R Stirling engines provide a total power output of 2,900kW surfaced and 6,000kW submerged.
The Soryu Class is fitted with six HU-606 533mm torpedo tubes for Type 89 torpedoes and UGM-84 Harpoon anti-ship missiles. The Harpoon has a range of over 124km and speed of 864km/h.
Type 89 is a wire-guided torpedo with active and passive homing modes. It has a maximum speed of 130km/h and can engage targets within the range of 50km. The torpedo can carry a warhead of 267kg.

The Ministry of Defence has announced it will sign a contract for Astute boat seven.
According to the Ministry of Defence; the United Kingdom has finally decided to order a seventh boat, and the contract with BAE will be formalized this year.
Negotiations are ongoing and the contingent liabilities will come into force on signature of the contract.
The Departmental Minute describes the Contingent Liability that the MOD will hold as a result of placing the Astute Boat 7 ‘Whole Boat’ Contract, which will provide for the production and testing of the Vessel. The maximum contingent liability against the MOD is unquantifiable and will remain until the Out of Service Date of the submarine.
Within the Boat 7 contract, BAE Systems Marine Ltd limit their exposure to Product Liability to £1 billion per incident and £300 million in any 12-month period. This limits the contractor’s exposure for claims by the MOD for losses associated with the product being defective or deficient, and creates an exposure for MOD to third party claims against the contractor for losses associated with the product being defective or deficient. It is the view of the Department that the likelihood of any claim is remote.

Turkish defence company STM made an announcement on 28 February and stated that they have signed a contract with Pakistan Government to upgrade the Pakistan Navy’s second (of three) Agosta 90B submarine.
Accordingly, the project for the modernization of Agosta 90B class submarines was expanded by the addition of the modernization of the second submarine ship. Various additional systems, including the first submarine vessel, were added to the configuration, while all systems in the main contract were equally in the configuration of the second submarine vessel. In addition, the third submarine vessel and various additional systems with the contract amendment were also taken as options.
Pakistan signed for the three Agosta 90Bs in 1994 with the French company Naval Group (former DCNS). The lead-ship , PNS Khalid, was delivered to Pakistan in 1999, with the PNS Saad and PNS Hamza arriving in 2003 and 2006, respectively. These will be joined by eight new Hangor-class submarines (potentially S26) acquired from China by 2028.
The first submarine will be delivered in 2020. The modernization activities will be carried out on Karachi Shipyard & Engineering Works (KSEW) owned by the Pakistan Navy.
After an international bidding process, French company Safran Electronics & Defense has been chosen to deliver navigation system as part of the modernization project of the Royal Netherlands Navy’s Walrus-class submarines.
The Dutch Defence Materiel Organisation (DMO) was in charge of the selection process. In a joint statement, projects procurement officer Danny Pronk and senior naval systems integrator Jaap Hagesteijn, representing the DMO, said: “We chose Safran Electronics & Defense because we have great confidence in their long experience as a supplier of naval equipment.”
Sigma 40 navigation systems are built around a ring laser gyro (RLG) inertial core. The systems are deployed by more than 40 navies worldwide.
Poland is looking to acquire three new submarines to replace its remaining three, old Koben-class submarines.
Defense Ministry of Poland said they received offers from Germany, Sweden and France :
- France – Naval Group : Scorpene-class subs armed with MBDA’s naval cruise missiles
- Germany – ThyssenKrupp Marine Systems : 212CD-class
- Sweden – Kockum (SAAB) : A26-class
The Polish Defence Ministry spokeswoman, Col. Anna Pęzioł-Wójtowicz, said that “a final decision concerning the production of submarines will be made by Poland in the near future, after receiving replies from France, as well as from our other potential partners.”
The discussions form part of Poland’s Orka (Orca) programme, which costs EUR 2.4 billion, plan to acquire modern submarines for the Polish navy. Poland intends to purchase three to four submarines, which will be equipped with cruise missiles.
Once the contractor has been chosen, submarine deliveries are expected to start between 2024 and 2026.

The Egyptian Ministry of Defence announced that the Egyptian Navy’s first DCNS Gowind 2500 corvette (the Elfateh) and second (S 42) Thyssenkrupp Marine Systems (TKMS) Type 209/1400 diesel-electric submarine (SSK) arrived at a naval facility at Alexandria on October 18.
According to a statement by the Egyptian navy, the submarines have a range of 11.000 nautical miles, a top speed of 21 knots and displacement of 1.400 tonnes.
Egypt said the Type 209/1400s will be able to launch missiles and torpedoes – it is believed they will be fitted with Harpoon anti-ship missiles.
The new Type 209s will most likely replace the Egyptian Navy’s four elderly Romeo class vessels delivered in 1983/84.
The Gowind 2500 displaces at 2,600-tons and is armed with a 76-mm main gun, two 20-mm cannons, two quad-cell MBDA Exocet anti-ship missiles (AShM), two-triple anti-submarine warfare (ASW) torpedoes, and a 16-cell SYLVER A35 vertical-launch system (VLS). The SYLVER VLS can house surface-to-air missiles (SAM) such as the MBDA MICA-VL (20 km) and MBDA Sea Ceptor (25+ km).
During the trip to Egypt, the corvette participated in a drill with the French navy in the Atlantic ocean. The deal is part of the armed forces support for “combat and technical capabilities” of naval forces, according to the Egyptian army official spokesperson.
Egypt has four Gowind 2500 corvettes on order under a €1 billion order from France in 2015 and four TKMS Type 209/1400 SSKs from Germany in 2012.
