Great news! Maybe CLGM or CLGM 2.0. Hopefully will be inducted not just with Arjun but also with Rudra & LCH. Will be a cost-effective weapon for both ATGM and LOC-jihadi-hunting!Can be our laser-guided Hellfire equivalent
More like a AGM-176 equivalent though not sure whether the -176 has a armor defeat mission/requirement and warhead optimized variant [yet]. With the size, weight and other characteristics (of CLGM) the platform possibilities, over time, are endless.

Not really. Russia and the US has had plenty of scramjet engine testing and demonstrations across the envelope and mach numbers. Going back years and in some cases decades. Foundational research and many scramjet test (known) records are held by these systems. China likewise, has, supposedly, made good progress there as well. The X-43 and the X-51 did a lot of the advanced flight demonstrations, and proved, and disproved, many ground testing assumptions. X-51 was first to cross the 200-second scramjet burn time milestone in actual flight testing about a decade ago. Only difference, it used a two-stage set up to get it to that 80,000 ft altitude (first stage - 0.8 M launch at 49K ft (B-52), second stage - Rocket motor to get from 50K feet up to the engine-ignite altitude of between 65,000 ft. and 80,000 ft).
Full up scramjet powered weapon systems are now in flight testing in Russia (Tsirkon) and the US (HAWC) and are expected to be fielded on a 2-4 year horizon. Affordable component manufacturing (at scale) and meeting full weapons envelope is still a hard challenge to solve. Boost Glide weapons (particularly if you can get the more exotic shapes that allow for prolonged glide) are atractive beyond a certain mission range because they have a much faster speed, and thus time to target, compared to what's possible with current scramjet technology levels. There you are looking at average weapon speeds of between Mach 11 and Mach 14 and peaks closer to Mach 20. Still slower than a ballistic missile but you are getting better than 50% non-ballistic flight so you don't alert BMD EW and make easy/early PIP calculation extremely hard. But, relative to scramjet powered systems, they are larger, heavier and harder to integrate on platforms because you are buying all that speed upfront, vs generating it along the way as with a scramjet (that accelerates).
