Missiles are quite different from Humans. sustained 5-7G's of force is quite negligible to have any effect on equipment, you can see 2-4G's acceleration on accelerometers by just dropping them as momentary reactions. You would be surprised at the measurements of a motorcycle hitting a pothole at 40mph.
Supersonic speed and air friction has minimal effect on the missile or even on the aircraft itself by themselves. Reaction forces that the airframe sees on the account of stress due to the forces generated by the velocity and resultant lift/drag have fatigue effects on the control surface itself. But Velocity and friction by themselves have a negligible effect. Now looking at the ordinance and stress on it, given unlike the Airframe, they are not stress members they will have a negligible effect on the missile/bomb frame itself. Also, the control surface on the missile are extremely small and thus has minimal reaction forces on the frame.
Moisture is an interesting area, most of the effect of moisture actually happens on a unit when it is stationary at sea level. The biggest problem with moisture is of condensation and it can cause catastrophic failure on systems. In some systems, there are mitigation techniques such as service outlets for dry air blowouts, especially in targetting pods, refueling systems, even ground refueling vehicles. In most missiles effect of moisture depends on the design if the manufacturer calls for canisters for storage and Vac treatment and it's not stored in proper mechanism then there is possible degradation especially if the subsystem was not certified for high humidity operation. Fortunately in Indian Air Force, most Russian equipment goes through salt spray tests, rain tests, etc to be certified for their own use. All of this documentation is available to the procurement agencies. Even the paint that IAF uses for its aircraft and ordinance is fully certified.
So there is a very very low chance that there will be rapid degradation of the missile unit because it was on the fighter Jet.
Sir
Many thanks for such a detailed explanation
Actually in BR Forum I read that
All our Air to Air Missiles Will be totally ruined in 15 days if we went for 24 / 7 CAPS
I would take that with a grain of salt.
There are trained ground staff that specialize in ensuring the ordinance will be effective, which includes removing the ordinance from the aircraft and running checks on the seekers, booster engines, pre frag box, fuse, etc on a TPM routing even during combat and any missile which has been on an aircraft for certain cycle time will get an inspection cycle. Even the 20mm and 30mm ammo boxes have routine changeovers.

Wait for FOC LCA-Tejas Gets longer
IAF’s will have to wait little longer after First Four Final Operational Clearance (FOC) configuration LCA-Tejas aircraft which was scheduled to be delivered by HAL by end of March this month is likely to miss its target schedule due to last-minute changes and upgrades carried out on the first four LCA-Tejas to come out in FOC Configuration. First FOC configured SP-21 carried out its Ground engine run, way back in November and it was decided it will get its crucial software upgrade from its partner Aeronautics Development Agency (ADA) to allow integration and firing of newer weapons along with the ability to handle the better rate of climb with better communication systems. while HAL is still tight lipped about why SP-21 is yet to fly but sources close to **** have informed that due to teething issues with some of the FOC equipment integrated for the first time and due to minor software related issues both SP-21 and SP-22 are held up as a precaution from carrying out it first flight, while SP-23 is almost ready and work on SP-24 is already at advance stage of completion, HAL is trying to get at least SP-21 and SP-22 airborne by end of March and SP-23 and Sp-24 in next two months so that expected commissioning of second squadrons of LCA-Tejas Mk1 in IAF happens by end of June or in July with four aircraft. what was supposed to be quick last-minute component swap and software upgrade has become a bottleneck in delivery of first FOC configured LCA-Tejas what that is holding back both the aircraft. HAL is maintaining that production of SP-25 to SP-31 is progressing well and has maintained that for FY-2020-21 it will deliver another 8 LCA-Tejas Mk1 above Four FOC LCA-Tejas it had promised to deliver by end of FY-2019-20. Last LCA-Tejas Mk1 in IOC-II configuration to come out of HAL Production line ironically was SP-16 (LA-5016 ) which had completed its maiden flight after taking off from HAL Airport in Bangalore on 12-March-2019 which is almost a year back, since then HAL started preparing for manufacturing of FOC configured LCA-Tejas which starts from SP-21 onwards. Air Chief Marshal Rakesh Kumar Singh Bhadauria already has confirmed that the first LCA-Tejas No. 45 Squadron ” Flying Daggers ” based at Air Force Station Sulur will move out to a forward airbase in the western sector close to Pakistan by end of this year and second LCA-Tejas Squadron will soon be established by mid of this year once first four aircraft are delivered by HAL at Air Force Station Sulur. Sources close to **** have confirmed that the second squadron will move out of Sulur by end of 2021 to a forward base in Jammu and Kashmir.

Looks like LCA Tejas sp21 FOC Version had its first flight today. Could be unofficial before tomorrow's official first flight......
☺
Nope, the ground tests are going on. Tomorrow probably.

There's always one short unofficial flight before the official flights in front of VIPs, press and audience. So this could be the one and may be not but definitely tomorrow there will be first flight....
When Tejas first flew in 2000, the times of India article said it will take 10-12 years for it to be combat ready. My first reaction was “ What the hell.. 10 years ?? Why should it take that long ??”
Well .. It took 20 years

Tejas project should be counted from April 2010 onwards when LSP 3 first flew with a functional Radar
LSP 3 was the first proper fighter plane
Before that the project always had the possibility of being Shut down permanently
UPA government wanted to close it down permanently
