-#Pakistan & its #Navy becoming butt of jokes for its ridiculosity
-It regularly finds submarines at high seas & that too #IndianNavy submarine
-Finding enemy submarines in real-world situation is like finding needle in haystack
-This clearly shows unprofessionalism of Pak Forces

2️⃣
-I hv flown enough missions to debunk claim
-At times finding surface ship becomes Herculean task
-Submarines can be found using physics & array of hi-tech sensors
-Acoustic sensors look for sound pr waves under water
-Electromagnetic sensors identify various parts of spectrum

3️⃣
-Active sensors emit ping & collect returning signal that has reflected back from submarine
-Passive sensors listen noise in environment & hope like hell that it is from the target
-Sonobuoys with hydrophoneare dropped in sea
-They look out for noise & transmit it to aircraft

4️⃣
-Sonobuoys are 2 type active & passive
-Effectiveness highly dependents upon local environment
-They hv rage of just 100-500 mtrs
-Another Eqpt Magnetic Anomaly Detector detects minute variations in the Earth’s magnetic field
-Metallic sub disturbs Earth’s magnetic field

5️⃣
-MAD could be placed at end of a boom or as towed device
-After doing all this to detect a submarine, it must be very close to aircraft position & close to sea surface to produce detectable anomaly
-Radar, visual, catching radio transmission etc other ineffective ways
