which is the first nuclear submarine to be designed and built in india
Arihant-class submarine The Arihant-class submarines are nuclear powered ballistic missile submarines built under the Advanced Technology Vessel (ATV) project.[21][22][23][24][25][26] They will be the first nuclear submarines designed and built by India.[27] The submarines are 112 m (367 ft) long with a beam of 11 m (36 ft), a draught of 10 m (33 ft), displacement of 6,000 tonnes (5,900 long tons; 6,600 short tons) and a diving depth of 300 m (980 ft). The complement is about 95, including officers and sailors.[28] The boats are powered by a single seven blade propeller powered by an 83 MW (111,000 hp) pressurised water reactor and can achieve a maximum speed of 12–15 knots (22–28 km/h) when surfaced and 24 knots (44 km/h) when submerged.[28]
Agra Sh훮h Jah훮n later shifted the capital to Delhi during his reign, but his son Aurangzeb moved the capital back to Akbarab훮d, usurping his father and imprisoning him in the Fort there. Akbarab훮d remained the capital of India during the rule of Aurangzeb until he shifted it to Aurangabad in the Deccan in 1653.
Subhas Chandra Bose Bose arrived in Germany in April 1941, where the leadership offered unexpected, if sometimes ambivalent, sympathy for the cause of India's independence, contrasting starkly with its attitudes towards other colonised peoples and ethnic communities.[11][12] In November 1941, with German funds, a Free India Centre was set up in Berlin, and soon a Free India Radio, on which Bose broadcast nightly. A 3,000-strong Free India Legion, comprising Indians captured by Erwin Rommel's Afrika Korps, was also formed to aid in a possible future German land invasion of India.[13]  By spring 1942, in light of Japanese victories in southeast Asia and changing German priorities, a German invasion of India became untenable, and Bose became keen to move to southeast Asia.[14] Adolf Hitler, during his only meeting with Bose in late May 1942, suggested the same, and offered to arrange for a submarine.[15] During this time Bose also became a father; his wife, [16] or companion,[17][j] Emilie Schenkl, whom he had met in 1934, gave birth to a baby girl in November 1942.[16][11] Identifying strongly with the Axis powers, and no longer apologetically, Bose boarded a German submarine in February 1943.[18][19] In Madagascar, he was transferred to a Japanese submarine from which he disembarked in Japanese-held Sumatra in May 1943.[18]
Ganges In November 2008, the Ganges, alone among India's rivers, was declared a "National River", facilitating the formation of a National Ganga River Basin Authority that would have greater powers to plan, implement and monitor measures aimed at protecting the river.[131]
