터키가 하푼을 대체해 자국산 Atmaca 대함미사일을 전투함 11척에 탑재할 예정이라고 합니다. 이스탄불급 프리깃, 개량형 메코 200TN급인 바르바로스급 프리깃, 에이다급 코르벳에 장착될 것 같다고 하는데, 위키를 참조하면 해당 함정은 총 9척+취역 예정 3척으로 12척인데 왜 11척인지..
교체되는 수량은 350발 이상으로, 가격이 하푼의 절반에 불과해 5억 달러 가량의 예산을 절감할 수 있다고 하네요.
Atmaca는 길이 4.3~5.2m, 중량 750kg, 탄두중량 220kg, 사거리는 220km라고 합니다. 하푼과 탄두중량이 같고, 길이는 60~70cm, 무게는 50kg정도가 더 나가네요.

Turkey to arm 11 naval platforms with Atmaca missiles

ANKARA, Turkey — Eleven of Turkey’s naval platforms will be armed with domestically produced Atmaca anti-ship missiles as part of a deal with state-controlled missile maker Roketsan and government-owned defense technology entity STM.
Roketsan developed the Atmaca system with surface warfare in mind. The weapon is a high-precision anti-ship missile that can arm assault boats, frigates and corvettes.
Roketsan says the system is autonomous, has a low radar cross section, can operate in all weather conditions, and features resistance to countermeasures. The company also boasts a 3D mission planning capability as well as target-update and mission-abort features via data link.
The Atmaca can fall between 4.3 meters and 5.2 meters in length. It weighs 750 kilograms (1,653 pounds) and has a range of 220 kilometers (137 miles). The system’s warhead weighs 220 kilograms.
It uses both an inertial navigation system and global positioning system for guidance.
The Atmaca will replace Turkey’s aging inventory of more than 350 American-made Harpoon missiles. STM said the integration of Atmaca missiles to the naval platforms will be completed by April 11, 2027.
Turkey will likely equip I-class frigates, the upgraded Barbaros-class Meko 200 TN and Ada-class corvettes with the Atmaca, according to Ozgur Eksi, an Ankara-based defense analyst.
Roketsan won the development contract from the Turkish government in 2009. In 2018, Roketsan teamed up with military-electronics specialist Aselsan, Turkey’s largest defense firm, to jointly manufacture Atmaca, which incorporates features of the Harpoon weapon and the French-made Exocet missile.
The Turkish government is expected to save up to $500 million by choosing the Atmaca to replace its Harpoon missiles, as the homemade weapon is about half the price of the American-made option.
Atmaca’s land variant, known as the Kara Atmaca, is a jam-resistant, long-range cruise missile system launched on tactical wheeled vehicles.

첫댓글 INS와 GPS를 쓴다고 하는데 GPS는 상용이겠죠?
"a 3D mission planning capability as well as target-update and mission-abort features via data link"에서 데이터링크도 언급하는데 미사일이 낮게 날아서 가면 UAV나 헬리콥터가 미사일과 line of sight가 유지되도록 떠 있어야만 할 것 같습니다.
다른 나라 대함미사일 사례를 참고하자면 민수용 GPS와 글로나스/갈릴레오를 동시에 수신하는 수신기를 장착했을것 같습니다.
@김민석 상용 항법 위성의 전파는 다 받는 것 같네요.

재밍에 대한 얘기는 여기에 있고요. 물론 대함 미사일은 INS 오차 보정에나 GPS를 쓰고 종말 유도에는 레이다 탐색기를 쓰니 GPS에 의존하는 JDAM과는 사정이 다르긴 하지요.
