This is coolbert:
From that previous blog entry and according to the DEBKAfile:
"Iran has additionally weighing the purchase in Moscow of 250
highly-advanced Sukhoi-Su-30MK1 twinjet multirole air superiority
fighters, known in the West as Flanker-H."
"Iran orders from China 150 J-10 fighter jets that incorporate Israeli technology"
Flanker has been found to have a major shortcoming. To carry eight tons
of ordnance, it must use both of its AL-31FP engines, and the transition
from one to two – and the reverse - often causes engine failure."
Indian Air Force has reported three such malfunctions in a month, as
well another shortcoming: The time needed for making the aircraft
serviceable is too long. As a result, only half of the Indian fleet can
be airborne at one time."
AND as extracted from a Strategy Page article previous Soviet and now Russian warplanes of the MiG variety not so absolutely the best and effective. Having serious difficulties as now recognized and across the board but only with hindsight:
"All this is
part of the decline of the once feared, and admired, MiG combat
aircraft. Starting in World War II (the MiG-1 entered service in 1940),
through the Korean War (the MiG-15 jet fighter), and the Cold War (the
MiG-17/19/21/23/27/29) MiGs comprised the bulk of the jet fighters in
communist, and Indian, air forces. But after the Cold War ended in 1991,
the flaws of the MiG aircraft (poor quality control and reliability,
difficult to fly) caught up with users in a big way. In the last few
years most of the bad news about military aircraft reliability,
accidents, and crashes has involved MiG products."
The MiG-15 from the era of the Korean War in a tight and steep turn the jet engine for whatever reason having a bad tendency to SHUT DOWN!
That MiG-21 also when two-thirds [2/3] of the fuel being consumed becoming unconditionally unstable, hard to fly, crashing a lot on landing!
