1. SSBN. Dhanush missile.
2.Jalashwa can be used for offensive purposes, like we can buy billions of $ worth of Russian equipment, can nuke any country, can trade nuke tech with Iran, NK, can build ICBM and can nuke US, nothing is impossible, but why, Jalashwa can n't use in any military role, both in offensive and defensive under Indo-US agreement.
Till date relations with France is great, but with US, its worse, a nightmare. P8 brought by GoI to make US happy, MH-60R brought becz it is best in the class, less expensive, share common elements with P8I, and both are defensive platform, not offensive, like SAM. Buying from France & US is very different, from France - expensive, zero sanctions, steady supply of spare and parts.
3.Since its IN thread. relations with US, French is very relevant, they consider all before making a choice.
