Isreal has no experience?

Care to check this link?

Israeli Aircraft Industries manufactures an upgrade package for the MiG-21 called the MiG-21-2000

the link says;

If required, the MiG-21 2000 can be fitted with an EL/M-2032 radar, developed by IAI Elta Electronic Industries, based in Ashdod. The radar, which uses a low sidelobe planar array antenna and pulse Doppler beam sharpening, provides all-altitude, all-aspect look-up/look-down and shoot-down capability.

Is this the same ELTA 2032 radar that JF17 is going to equip in future?

Yes it might be the choice for chinese FC-1s.

Elta EL/M 2032:
Air-to-Air detection and tracking range up to 80 NM.

The EL/M-2032 is an advanced Multimode Airborne Fire Control Radar designed for multimission fighters, oriented for both air-to-air and strike missions. Modular hardware design, software control and flexible avionic interfaces ensure that the radar can be installed in fighter aircraft (such as F-16, F-5, Mirage, F-4, Mig 21, etc.) and can be customized to meet specific user requirements. The EL/M-2032 radar integrates ELTA's experience with real operational feedback from Israeli Air Force combat pilots.



The EL/M-2032 greatly enhances the Air-to-Air, Air-to-Ground and Air-to-Sea capabilities of the aircraft. In the Air-to-Air modes, the radar enables long-range target detection and tracking for weapon delivery or automatic target acquisition in close combat engagements.

In Air-to-Ground missions, the radar provides very high-resolution mapping (SAR), surface target detection and tracking over RBM, DBS and SAR maps in addition to A/G ranging. In Air-to-Sea missions the radar provides long range target detection and tracking, including target classification capabilities (RS, ISAR).

is EL/M-2032 is better than F-16s AN/APG-68 V(5) radar?

I dont think age of airframe that is the determining factor in frequency of crashes. After all the U.S. is planning to use B-52 bombers untill some of them are 100 years old.

The determining factor is the amount of stress that the airframe undergoes. This is determined by two factors, firstly how long the airframe is in flight and how it is flown while in flight.

For e.g. Egyptians fly their F-16's only at 3G compared to Isaelies who fly at 6G in training. (G forces = the amount of acceleration that an entity undergoes. You are currently experiencing 1 G because of Earths gravitational field. At 10G without specialised suits and training, most people become unconsioucess.)

Therefore Indians should reduce the number of G's that their Mig-21's pull in training and also should reduce the amount of Airtime their undergo. Or better still, they shoudn't fly at all.

Bigger aircrafts always have a greater service life than the fighters.

MiG series aircrafts are generally designed for 25 years of active service life.

So one cannot compare MiG-21 and B-52 in service life scenario's.

Also read.

B-52 Stratofortress Service Life

Updated with modern technology, the B-52 will continue into the 21st century as an important element of US forces. There is a proposal under consideration to re-engine the remaining B-52H aircraft to extend the service life. B-52 re-engine plans, if implemented, call for the B-52 to be utilized through 2025. Current engineering analysis show the B-52's life span to extend beyond the year 2040. The limiting factor of the B-52’s service life is the economic limit of the aircraft's upper wing surface, calculated to be approximately 32,500 to 37,500 flight hours. Based on the projected economic service life and forecast mishap rates, the Air Force will be unable to maintain the requirement of 62 aircraft by 2044, after 84 years in service

The May 1997 Report of the Quadrennial Defense Review (QDR), prescribed a total fleet of 187 bombers (95 B-1, 21 B-2, and 71 B-52). Since the QDR, two B-1s had been lost in peacetime accidents. However, the Report of the Panel to Review Long-Range Air Power (LRAP) concluded the existing bomber fleet cannot be sustained through the expected life of the air frames and that additional aircraft will eventually be required. To address this issue, the Air Force will add five additional B-52 attrition reserve aircraft, bringing the B-52 total from 71 to 76 for a total bomber force of 190. The B-52 fleet will remain the same with 44 combat-coded aircraft.

Since those studies, the Air Force has decided to retire 33 B-1s and 17 B-52Hs, reducing the current fleet of 208 bombers (93 B-1s, 21 B-2s, 94 B-52Hs) to 157. Of these bombers, only 96 will be combat coded, with the rest used for backup and other purposes. The B-52H and B-2 still retain a conventional and a nuclear mission, while the B-1 is roled for the conventional mission only.

The B-52H was designed as high altitude aircraft, but was adapted to low level tactical maneuvers in 1960’s. A number of structural improvements were made during the 1960s and 1970s to equip it to fly the more demanding low- level mission and to address other structural issues.

The airframe life for the current fleet is estimated to be between 32,500 and 37,500 hours, depending on the usage history of the individual aircraft. The estimate is based upon scaling measurements from a full-scale test structure using assumed mission profiles along with historical and projected usage information. The upper wing surface is expected to be the life- limiting structural member. As of 1999 the average airframe had 14,700 flight hours. Boeing believes with high confidence that the average number of flight hours left is 17,800, at a minimum. The “oldest” B-52H is at about 21,000 hours and only experiences about 380 flight hours per year.

So before coming up with claims of 100 years service life and all be a little bit calmed down.
