I might be wrong, but it looks like the Ramjet is an add-on propulsion kit on ERFB (extended range full bore) arty shells, unlike other projects elsewhere with internal Ramjet in the front like BrahMos.
A Happy News on an otherwise Sad Day ( ISRO failure )
Anyway it looks like we need a lot of Divine Blessings and Help for all our programmes To succeed

I think most of us are ignoring the possibility regarding whether it will fit in the load-assist contraptions in Dhanush, ATAGS, MGS, K9, etc or not. The tweet did say, that they tested it in the aforementioned systems, but I still have doubts.
The firing pic is a Sharang, which is all manual.
Or maybe it's supposed to be a special limited ammo which will have to loaded "somehow" and it's left to the crew about how they do it (sounds stupid).

How does it affect precision/CEP?, Question no one asking.
It will increase CEP at those ranges. But since it's a plug-in modul it can be used on our guided shells once ready. Or, if we can get GNC fuses like M1156 PGK.
Any attempt at increasing range through base devices will introduce instability problems at longer ranges. Same thing happens with Base bleed, boat tail etc..devices. Accuracy will need trajectory correction devices.
Zues Numerix is making some under IDEX:
Lt Gen P.R. Shankar was the First person who created the awareness about The Potential of Ramjet Artillery
Above tweet seems to address the mistake of omitting couple of involved personnel related, not any new information.
Ramjet assisted shell and ramjet shell in theory would be 2 different things , this and the drdo made one.

40--->70.
36---> 62
30--->55
Shows improvement of 70%-80% over original range.
Yet claim is nearly 50% improvement?
Is the 70-80% improvement in range is in test conditions at optimal angle? And they are playing it safe for wide range angles of fire in wide set of conditions and environment, by using 50% improvement ?
Yes range test firing possibly max distance achieved. To pair with accuracy , estimate of 40-50% average would be natural under normal ambient condition which might vary for different theater. Range firing are obviously safety first.
Army has mentioned a substantial the need for assisted artillery shells in the TPCR. Range requirement is upwards of 60km. IITM's shell can fulfil this requirement although ARDE is also working on a rocket assisted shell.
Yes I remember this, its a future project, that is to be made ready in the next 5+ years. So a medium to long term approach. Much like Pinaka which is evolving, new tech infusion try to accommodate new systems and make use of older stock in some innovative way.
I think it's longer than that. They are giving ranges conservative by 6-7km in their tweet.
Almost twice the range of previous.
~100% range improvement, which is again guess is at optimal range of angles.
But man that's a massive improvement.
Nearly 50% in tweet is big underplay, a nose guidance kit and accuracy problem will be solved, even 70-80% range improvement with guidance kit will be more than good enough
Is it the first of its kind in the world ? Because I couldn't find any such system to convert existing shells into ramjet propelled/powered shells .
General Shankar talks about the ramjet shell. Some important points:
1. NAMMO is the only competition. NAMMO's ramjet shell design is conventional & focuses on getting more range than inflicting massive damage. With this design the size of the warhead (~105 mm shell) will have to remain limited.
2. IIT-M's project was conceived 8 years ago, received official funding in 2020. COVID has delayed testing. IIT-M's Prof. Ramakrishna led this project with his student Dr. Yogesh Kumar Velari.
3. The design leverages existing 155mm shells. Take a 155mm BB shell remove the base device & attach this ramjet base attachment. Lethality remains the same as traditional 155mm shell.
4. Ramjet attachment can be fitted on any type of 155mm shell. Attachment can be done in the field by operators, doesn't require factory fitting. This will be a cheaper solution compared to other ramjet shells available. Additive manufacturing was used for prototyping.
5. Guidance will be needed. 5-6 types of guidance technologies are being looked at, options include GPS guidance, INS guidance for GPS denied environments etc.
6. The ramjet & guidance technologies can be used on 122mm GRADs to increase range & accuracy.
7. There are some issues that need to be worked out. Like how this round will work with artillery guns will that have a magazine & autoloader. If testing proceeds well this round would enter service in 2-3 years.
