I can't get over how good the ALH/Rudra looks in IAF colours! The IA's paint schemes are rather childish by comparison.

Would the turret be covered like that of the LCH?
 
i dont think theres a need to cover it as it would be more aesthetic than functional

That cannot be definitely ascertained at this stage. I do not have the schematics of the gun turret with me, so I cannot say for certain, but most hydraulic-mechanical systems have a problem with dust/moisture/foreign object accumulation, potentially throwing off the careful alignment of the gun traverse.

It must be remembered that the turret is slaved to the gunner's sight. The gun points where the gunner looks. It is fairly plausible that the dust or foreign object could shake the alignment, or in the worst case scenario, lock the turret traverse. Such a scenario could require a trip to the BRD for unlocking and realignment operations.

Of course all of this is conjecture at this stage. Intensive trials and limited deployment would provide detailed assessment of the potential threat from dust/FO. Based on that you might require a gun cover.
 
quick question. the iaf jaguars were proposed to get the f125 engine over the upgraded adour engine which is currently in standard jags, so my question is which engine do the jags have now? and why?

All the current Jags are powered by Adour Mk811


Darin 3 will get F125

Jaguar with proposed upgrade engine Honeywell F-125IN at Aero India 2013

+++
Need for Upgrade
The IAF currently operates around 110 (5 1/2 sqns) Jaguar strike fighters powered by Rolls-Royce Adour-811 turbofan engines. The aircraft, which first entered squadron service in the early 80s, is optimized for strike after low level penetration of contested airspace. At medium altitudes, the Jaguar's maneuverability and acceleration are poor. As a result, the fighter is not suitable for stand-off close air support using Precision Guided Munition (PGM).

The IAF is making a doctrinal shift from specialized aircraft to multi-role aircraft, Based on fatigue analysis, the IAF estimates that Jaguars could remain operational till 2030. As a result, the IAF is keen to upgrade the Jaguar with more powerful engine, fourth-generation cockpit and mission avionics, and self protection suite so that it better fits IAF doctrinal thinking.

Upgraded Jaguars will feature all weather precision attack capability with enhanced weapon load.

Engine Upgrade
The Honeywell F125IN has a max thrust of 43.8kN. In comparison, the existing Rolls-Royce Adour Mk811 engine has a thrust of 32.5kN.

why dont they just go for the f125 all together since its better and dont you think its a nightmare going for many variants/specs for one platform.

Darin 3 upgrade is atm for all the birds who can serve us for another 15 years.(with engine part) Anything less in life or more fatigue in airframes does nt need such upgrades bcz it wont serve the purpose or the investment made. OF course after this whole batch of 60 plus jets , we might go forward and re engine the rest based on the assessment at that time.
