Have we indigenised R&D of the ramjets of any of the current iterations of the Brahmos? Aren't they all coming from Russia?
@Gautam
As far as I know here is how the ramjet engine IP of the Brahmos stands:
Brahmos Block I
In service limited in quantity
290km ranged
Cruise speed: Mach 2.8
Max speed: Mach 3
Limited Sea skimming capabilities
Engine: 3D55(100% Russian IP, manufactured at NPO Mashinostroyeniya)
Brahmos Block II
In service & widely available
290km ranged
Cruise speed: Mach 2.8
Max speed: Mach 3
Sea skimming at 10m
Capable of performing a terminal stage evasive "S" maneuver
Engine: modified 3D55 (Russian manufactured) with a new nozzle designed by DRDL & manufactured by Brahmos Aerospace
Brahmos Block III
In service & widely available
290km ranged
Cruise speed: Mach 2.8
Max speed: Mach 3
Sea skimming at 10m
Capable of performing a terminal stage evasive "S" maneuver
Steep diving capability for mountain warfare
Engine: modified 3D55 (Indian manufactured with a few critical parts like injectors imported from Russia) with a new nozzle designed by DRDL & manufactured by Brahmos Aerospace
Brahmos-A
In service limited in quantity
600km ranged
Cruise speed: Mach 2.8 (probably)
Max speed: Mach 3 (probably)
Sea skimming at 10m
Capable of performing a terminal stage evasive "S" maneuver
Steep diving capability for targeting bunkers
Engine: New unnamed engine designed by DRDL & Brahmos Aerospace based on the 3D55 design. Manufactured entirely in India by Brahmos Aerospace & its suppliers.
Brahmos Block IV
Under testing
Targeted range: 650km (Phase 1) to be upgraded to 800km (Phase 2) later
Range achieved so far: 400-450km
Cruise speed: ??
Max speed: ??
Sea skimming at 10m
Capable of performing a terminal stage evasive "S" maneuver
Steep diving capability for mountain warfare
Engine: The same unnamed engine as the Brahmos-A only larger in size. A new hydrocarbon based fuel has been developed for the Block IV with the intention of pushing the max speed to near Mach 5. The cruise speed (based on the fuel burn rate) will be set based on the target range.
Brahmos-A Mk-2(?!?!)
Under development/Not tested yet
Targeted range: 1500km
Engine: Probably the same as Brahmos-A but with the new fuel.
Brahmos-NG/Brahmos-M
Under development/Not tested yet
Targeted range: 290km
Targeted cruise speed: Mach 3.5
Engine: The new one except in smaller size than the Block IV. The overall missile is targeted to be 50% lighter & 3m shorter than the Block III variant, allowing the missile to be mounted on smaller ships of the Navy.
