잠수함 쿠바 해군의 소형 잠수함

함명 '델핀'으로 알려진 쿠바 해군의 소형 잠수함의 새로운 사진이 공개됐습니다. 

2008년 4월 상업위성사진으로 존재가 드러났지만 쿠바 해군의 공식적 정보 공개는 없었는데, 최근 쿠바해군의 공식 사이트에 사진이 올라왔다고 하네요. 

길이는 70피트, 선원은 5명 이상에 중어뢰로 무장했다고 합니다. 소나는 함수 대신 세일의 리딩엣지에 장착됐고, 능동소나세트인지 여부는 불확실합니다. 

잠수함 외에 특작요원 2명 가량이 탑승 가능할 것으로 보이는 SDV의 사진도 공개됐습니다. 1950년대에 개발된 이탈리아제 시호스와 트라스 SDV와 비슷해 보이지만, 흡착기뢰 대신 21인치 중어뢰 한 발을 선체하부에 부착한 것이 차이점입니다. 잠망경이 없어 어뢰를 조준하기 위해선 부상할 필요가 있습니다. 이런 식으로 어뢰를 장착한 SDV는 드물지만, 1980년대에 실험했었던 SEAL의 Mk IX SDV가 Mk.37 두 발을 선체 양측에 장착 가능했었다고 합니다. 

미젯과 SDV 모두 제대로 운영된다면, 2010년 천암함의 사례에서 보듯 상당한 위협이 될 수 있습니다. 

New Photos Reveal Details of Cuba’s Tiny, Lethal Attack Submarine

Like most of the Cuban military, the country’s Navy is characterized by inventive recycling of Soviet-era hardware. Modern systems are rare, but there are systems that are unlike anything you will see in other countries’ fleets. The Cuban fleet has fishing trawlers remodeled into warships and torpedo launching platforms that resemble party rafts. But perhaps the most dangerous platform is Cuba’s secretive, tiny submarine.

The single submarine is known as Delfín. It can be found in commercial satellite imagery going back at least as far as April 2008. A few candid photographs have emerged over the years, but it has not been showcased publicly until recently.

The Cuban Navy has been very secretive about the mere existence of this submarine. In more than ten years of service, Delfín was only shown in an official video this year. Now the guard has come down even further and a clear photograph of this unique submarine has been added to their official website.

Delfín is a small boat – about 70 feet (21 meters) long. It has a crew of 5 or more and is armed with heavyweight torpedoes. The main sonar appears to have been built into the leading edge of the sail instead of the more common bow position, according to a photo released by the Cuban government. It’s unclear from the photo if the installation is an active sonar set, which could limit its potential to surprise warships.

But submarines, even small and unsophisticated ones, cannot be easily discounted. If well-crewed and commanded they can pose a serious threat in their local area. In 2010, a North Korean miniature submarine successfully sunk the South Korean corvette ROKS Cheonan in 2010. It is perhaps because it is the most threatening vessel in their fleet that Cuba has been so keen to hide it.

Delfín was not the only submarine recently shown in the new photos. Information about Cuba’s domestically developed SDV (Swimmer Delivery Vehicle) has also been slipping out over the years. Based on the variety of hull numbers seen to date there are likely a handful of these craft in service. On the surface, the Cuban SDV bears some resemblance to the Italian-made Seahorse and Trass vehicles of 1950s vintage. These were used by the U.S. Navy SEALs and UDT (Underwater Demolition Teams) could have informed the Cuban Navy’s design.

But the current vehicle is not a direct copy – it only follows the overall arrangement. Two or more divers sit in an open cockpit over a sealed tube containing the batteries and a single electric motor.

Where the Cuban SDV differs significantly from the Italian types is in its armament. Instead of limpet mines, a single 21-inch heavyweight torpedo is suspended under the fuselage. The torpedo appears to be a vintage Type-53 series Soviet one.

Without a periscope for aiming, the SDV may have to broach the surface for the pilot to align the vehicle with the target. Very few other SDVs are armed with a torpedo-like this. The most obvious precedent are German sneak attack submersibles of World War II. But these were unsuccessful. More recently, in the 1980s, the U.S. Navy’s experimented with its Mk IX SDV that could carry two modified Mk 37 torpedoes, one on each side.

These submarine devices do compare to the latest Western types, but underwater craft can never be completely written off. If used in the right way, they can cause considerable concern for a potential adversary, as seen by the 2010 sinking of Cheonan.

Delfin이면 러시아식 이름인데 쿠바가 직접 만든 것으로 묘사되어 있네요. 옛날 유고슬라비아도 이런 잠수함을 만들었는데...

북한의 연어급도 있구요. 하긴 요즘은 마약밀매조직도 잠수함을 굴리는 세상이라..

서방측에서는 이탈리아의 COSMOS가 있었죠.
