The "Sea Lion" and "Sea Seal" were built by the US military in the 1940s and assisted Taiwan in 1973.Their service life has been nearly 60 years, and it is also more than 40 years since the implementation of the improvement of Jiapi 2 in 1958. Their hull has been quite aged, far from reaching the diving depth of the original design.Therefore, since 1995, "Sea Lion" class submarines have basically stopped going to sea and are mainly used forAntisubmarine warfareTraining.

Originally
Diesel electric submarine of the former US military during World War II
Former US ArmySecond World WarDuring this period, the diesel electric submarines were upgraded to the Gbi II function and handed over to the Taiwan Navy in the 1970s, mainly for training.The service status of submarines of this level has always been highly mysterious, and the equipment status only has various rumors for reference.It is rumoured that when this class of ship is handed over,torpedoThe tube has been sealed by the US military, unable to launch torpedoes.However, the Navy said that the torpedo firing circuits of the two submarines were normal, and there were mines installed for training.The Navy once bought modern torpedoes from Europe.However, the usable torpedoes of submarines in World War II had been out of production for many years. Whether they were armed was unknown.In 2005, the Chinese Taiwan Navy made an exception to the public display of seal warships, which attracted a large number of visitors.This class of ship is the oldest diesel submarine in service in the world, and has been in service for more than 60 years.The Taiwan Navy is planning to propose to the "Ministry of Defense" of the Taiwan authorities to purchase new submarines for replacement. However, due to budget problems, the following has been delayed.
This class of ships has been in service for more than 60 years, setting a record of the world's participation in World War II and still in service. Japanese professional magazines have featured the world's oldest submarine in service for half a century, including Li Jie, the former "Minister of National Defense" of the Taiwan authorities, who also served in this class of ships,However, the last two ships of this class still have certain combat capability due to the marvelous maintenance of the Taiwan Navy.The well-known Discovery also required to shoot a TV album on this class of ships, but after the shooting was completed, the Taiwan Navy, citing military secrets of active ships, required that this class of ships must be decommissioned before broadcast.
Due to the shortage of naval submarines in Taiwan, it is understood that if new submarines are not replenished all the time, this class of ships will continue to serve.Taiwan's "Sea Lion" class submarine was originally a "Freshwater Carp" class submarine of the US Navy.The submarine "Sea Lion" (SS791), formerly the "Carp" (SS426) of the US Navy, was launched in July 1945, delivered to Taiwan in 1973, and arrived in Taiwan in January 1974;The same boat "Seal" (SS792), formerly the US Navy "Angolan Hairtail" (SS478), was launched in November 1944, delivered to Taiwan in April 1973, and arrived in Taiwan in April 1974.The "Sea Lion" class submarine was originally driven by the United States during the war. After more than 50 years of storms, its combat capability has been significantly reduced. Therefore, after 1995, the "Sea Lion" class submarine has basically stopped going to sea and can only be used as a training submarine to train the anti submarine combat capability of other ships.

Taiwan's "Legislative Yuan Taiwan American Association Friendship Association" visited the United States on September 21, 2014, met with U.S. officials in Washington, D.C., and briefed Taiwan that it would renovate its 70 year old GUPPY II submarine and start building its own submarine.Lin Yufang, the "legislator" of the Kuomintang, said that Taiwan had not sought the assistance of the United States to repair the Kebi class submarines, and the United States was concerned about whether Taiwan had a budget for submarines made by itself.
Taiwan Navy officials said that after Taiwan's "Legislative Yuan" passed the budget of nearly 800 million yuan for refurbishing old sea lion class submarines, it will open a bid in Taiwan, with Taiwan Ship as the main contractor, and then Taiwan Ship, Joint Construction Center and Navy Latent Repair Center will form a maintenance team.Because there is no suitable dock for the Taiwan ship, the replacement of the rear hull will be carried out in the naval dry dock. If the budget review is successful, it is expected that the maintenance works will be carried out in the second quarter.
Officials said that in the future, the submarine will choose a simpler configuration and temporarily put the air isolation system (AIP) on hold.The "Dart Project" is made for the NetherlandsHailong class submarineAdd submarine launchHarpoon missileThe first ship of the project is nearly completed and is expected to be launched in Taiwan waters.
Lin Yufang said that the United States had not been asked for assistance in renovating the Sea Lion class, and both Taiwan Ship and the Navy believed that they were able to replace the hull. However, in response to the unexpected problems of the original wall attached pipelines after the hull was disassembled, the renovation budget has been raised from 450 million yuan to 800 million yuan.Not only the United States but also European countries can provide technical assistance.However, the United States still needs to provide sensitive military equipment such as weapons and war departments.
Lin Yufang said that although the case of submarine sale to Taiwan has not been abolished, it has not yet been put into operation. The personnel of the submarine office for the US sale to Taiwan have all been put under construction. The US side has not proposed any assistance in the case of self made submarine sale to Taiwan.[1]
