インド、原子力潜水艦ATV進水へ。

各種公刊資料によると、インドは早ければ2007年には国産原子力潜水艦(ATV)を進水、2012年までに就役させる予定、とある。

Rajat Pandit, "N-submarine may be operational by 2012," The Times of India, 18 Mar, 2007, <http://timesofindia.indiatimes.com/N-submarine_may_be_operational_by_2012/articleshow/1776200.cms> (20 Mar 2007)本報道では、
"Though official word is hard to come by on the secretive ATV project, which formally kicked off in 1983 but has made excruciatingly slow progress since then, it's learnt that the first prototype of the nuclear-powered guided-missile attack submarine would be "launched" in the "near future".
"And if there are no more hitches, the first of the two ATVs should be ready for being commissioned into Navy by 2011-2012. The overall project cost has been hiked by 30% to take it to around Rs 14,000 crore, with ultimately five ATVs planned by around 2025," said a source." とある。(強調筆者)

Vishal Thapar, "India launches 1st nuclear submarine,"CNN-IBN, 19 Mar 2007,<http://www.ibnlive.com/news/india-launches-1st-nuclear-submarine/36394-3.html> (20 Mar 2007)より。
"INDIA’S OWN: Sea trials for the submarine are slated to begin by 2010, and are expected to be fully operational by 2012."
中略。
"The vessel displaces 6, 500 tonnes and can stay submerged for upto 100 days. Armed with guided missiles, it will have a crew of 70 people.
The last time the Indian Navy operated a nuclear submarine was in the late 1980s, when it leased a Russian Charlie class vessel.
India is also in negotiations to acquire two Russian-made nuclear submarines of the Akula class."

Rahul Bedi, "Indian SSN reactor fully online," Jane’s  Defence Weekly, AUGUST 30, 2006, p.15. では以下の如く報道。
"Indian defence and atomic scientists claim to have successfully developed the reactor for the country's long-delayed nuclear-powered Advanced Technology Vessel ( ATV) submarine (SSN) programme.
The 100 MWe reactor - developed jointly by the Department of Atomic Energy (DAE), the Defence Research and Development Organisation (DRDO) and the navy - went critical at Kalpakkam in southern India in October 2004, but official sources say that it is now "fully operational".
A miniaturised version is now under construction for integration with the ATV, which is being built at Visakhapatnam on the east coast.
The ATV is based on the Soviet-era Type 670A Skat (NATO designation 'Charlie' class) design - following experience gained during three years leasing a Russian Skat from 1988 - and is expected to be launched in 2007. The 124 m-long, 4,000 ton boat will then proceed to sea trials scheduled for 2009-10 over a decade behind schedule."(強調筆者)

なお2004年には、水中発射型のミサイル「プリトビⅢ(Prithvi)」が新型の発射器であるProject K-15  から発射されている。プラットフォームに関しては記載されていないが、2010以降に配備される予定であるり、2010年という時期はATVの就役時期と符合するものであると報じている。Andrew Koch,“India moves closer to sea-launched ballistic missile,” Jane’s  Defence Weekly, 10 Nov 2004, p.5.

DRDOが発行するTechnology Focus, Aug, 2004, にこの発射筒の記事が掲載されている。ここでは発射筒の材質について「海洋環境」における防錆対策を必要としない素材を用いていると紹介しており、海中発射システムであることが示されている。<http://www.drdo.com/pub/techfocus/aug04/missile13.htm>(28 Feb 2005).

2005年にはSLCMであるSagarikaの関連記事が掲載されている。本記事では、サガリカの射程が従来想像されてきた300kmではなく1,000kmを意図してきたことや、その射程を2,500kmへ延伸することを目標としていることが判明した。Vivek Raguvanshi, “Salvaging the Sagarika,”Defense News, 21 Feb 2005, p.14.

同ミサイル発射実験に関する報道。
"Cruise missile to be tested next year," PTI, 12 Nov 2006, <http://timesofindia.indiatimes.com/Cruise_missile_to_be_tested_next_year/articleshow/416869.cms>(12 Nov 2006)より。 "Sagarika, India's first submarine-launched nuclear-capable cruise missile, will be ready for flight trials by early next year, Defence Research and Development Organisation (DRDO) sources said.
The turbo-jet powered, vertically launched cruise missile with a range of 700 nautical miles and capable of delivering a 500-kg warhead, is being developed by DRDO with Israeli assistance. India is simultaneously seeking to rope in European missile firms for the project that is being kept under wraps.
The sources said the missile's first prototype, incorporating a solid fuel booster, should be ready for a test flight by early 2008.
At the same time, the DRDO is continuing the development of the submarine-launched version of the BrahMos supersonic cruise missile developed jointly with Russia"(強調筆者).

なお、例によってロシアはアクラ級リースに関する報道を否定。
"Russia denies rumours of leasing two nuclear submarines to India," Pravda, 19 Mar 2007, <http://english.pravda.ru/news/world/19-03-2007/88401-russia_india-0> (20 Mar 2007)より。"Russia's Federal Agency on Military-Technical Cooperation (FSVTS) denied the rumors published by Indian newspapers that two nuclear submarines of  project 971 Shchuka-B (NATO’s reporting name Shark) would be leased to India. However, it is noteworthy that there have been too many technical details in the published rumors which make it possible to assume that “there is no smoke without fire”, as they say in Russia. In particular, Indian sources claim that India and Russia have already signed the leasing agreement on the delivery of the two subs, having indicated even the sum of the contract - $ 350 million ($35 million for one submarine annually). Allegedly the contract was signed on January, 26th, 2007 during the visit of the President of the Russian Federation V.Putin to New Delhi."
