Trap
Japan is not allowed to export anything that can be used by military as a weapon, it's literally in their constitution.
The french offer is the most realistic one right now

Japa were progressing pretty nicely with their own jet engine program until, they were told ( threatened) by unkill to stop it

They would've been much bigger defence exporter than China if it wasn't for burgericans meddling

We still seemto be falling short of 85kn (GE 404in20) figure though intended wet thrust seems to be 78 to 80 kN figures which should be better than what we last heard about wet thrust of Kaveri as 70.4 kn.

If that figure of 80 KN is ISA which is what I think it is , then in normal conditions the output would be ~ 90 KN or 88 KN to be precise.

If that's the the case and Kaveri achieves that figure in stable manner with decent mtbf/mtbo then it would be fantastic.

it would be a game changer if true

No.
"Under Prime Minister Shinzo Abe, Japan relaxed its arms export rules:

The 2014 “Three Principles on Transfer of Defense Equipment and Technology” replaced the old policy.

Now, Japan can export defense equipment under strict conditions — such as contributing to peace and international cooperation."


Some exports and attempts( lost of competitors).

1. Patrol Boats to the Philippines (2016–2022)

Type: 12 40-meter multi-role response vessels.

Buyer: Philippine Coast Guard (via Official Development Assistance).

Use: Maritime security and anti-piracy (technically “non-lethal,” but military-grade equipment).

Builder: Japan Marine United (JMU).


2. Radar Systems to the Philippines (2020)

Type: Fixed and mobile air surveillance radars.

Buyer: Philippine Air Force.

Purpose: To strengthen air defense and detection of intrusions in the West Philippine Sea.

Manufacturer: Mitsubishi Electric.


3. Air Surveillance Radars to Indonesia (Approved 2021)

Type: Similar to the Philippine radar deal.

Buyer: Indonesian Air Force.

Manufacturer: Mitsubishi Electric.

Use: Border protection and maritime security.



---

Attempted or Proposed Exports That Fell Through

4. Submarines to Australia (2014–2016) – Failed Bid

Type: Sōryū-class diesel-electric submarines.

Details: Japan competed to supply Australia with new subs under the SEA 1000 project.

Outcome: Lost to France's Naval Group (now under review again as of 2021–2022).

We also got ToT for those Unicorn Radars for our frigates no??!! Japan is a natural partner for us, but US's stronghold isn't allowing it (more like drip feeding it). One of the reason Shinzo Abe is not in the world anymore!

Japan and India progress towards UNICORN stealth antenna deal - Naval News

Japan and India have agreed to proceed with the export to New Delhi of the UNICORN integrated stealth antenna system.

So, why Kaveri is limited to 1700K TET, while M88 has 1850K TET, when using similar materials?

Answer lies in air cooling of the blades, now another question is why couldn't we develop blades with similar air cooling, answer is We simply don't have the manufacturing capability, so the focus of our R&D should also be in development of Machine Tools, Instead of begging for these machine tools all around the world

ISRO Semicryo engine is facing delays precisely because of lack of manufacturing know-why, NOT design Know-why, they are struggling with brazing of Regeneratively cooled Combustion chamber & Nozzle

My only grouse is why this system is not pointy ?
It looks like a thingy stacked upon a ship.

Current DMS4 alloy + YSZ-LZ based Bi-layer TBC combination can also reach 2100K TET if we use proper air cooling architecture in the blades ,but for that we have to develop a method to SC casting of blades with proper internal channels and also develop Laser drilling Machine Tools to drill very very tiny holes
