Aryabhata was India's first satellite, launched on April 19, 1975. It was named after the ancient Indian mathematician-astronomer Aryabhata. Agni and Prithvi are missile systems, not satellites. Chandrayaan came much later as India's first lunar mission in 2008.

Arvi in Maharashtra housed India's first experimental Television Reception Centre, established in the 1960s to test TV transmission technology before regular broadcasting began. This was a technical facility for receiving and testing TV signals, not a broadcast studio like later centers in major cities.

India's first telephone system was established in Calcutta (now Kolkata) in 1881, just five years after Alexander Graham Bell patented the telephone. The colonial capital had the earliest telecommunications infrastructure, preceding telephone systems in other major cities like Bombay (Mumbai) and Madras (Chennai).

India's first railway line opened between Mumbai (then Bombay) and Thane in 1853, covering 34 kilometers. This was the commencement of railway transport in India, built by the Great Indian Peninsular Railway. The route connected the commercial hub to its neighboring town, not to distant cities like Goa, Delhi, or Pune.

India's first postage stamps were issued in 1854 from Karachi, which was then part of British India (now in Pakistan). These were the Scinde Dawk stamps, embossed with designs. Agra, Calcutta, and Thane were major postal centers but not the site of the first stamp issue - this is a common point of confusion with where stamps were used versus where they were printed.

Germany was the first country to use submarines (U-boats) effectively in warfare during World War I, revolutionizing naval combat with unrestricted submarine warfare.
