Operation Dwarka is one of the most significant events of 1965 Indo-Pak war which reflected courage, determination, professional competence, dedication and coordination of the PN personnel involved in it. The objectives of this operation were:-
a. To draw the heavy enemy units out of Bombay for the submarine GHAZI to attack
b. To destroy the radar installation at Dwarka
c. To lower Indian morale
d. To divert Indian Air effort away from the north.
On 7 September 1965 when the ships were on their normal war patrol, the following signal was received from Naval Headquarters:-
“Task group comprising PNS BABUR, PNS KHAIBAR, PNS BADR, PNS JAHANGIR, PNS ALAMGIR, PNS SHAHJAHAN and PNS TIPU SULTAN is to be in position 239 degrees 120 miles from Dwarka light house by 071800 E Sep with maximum power available. Task group thereafter to carryout bombardment of Dwarka about midnight using 50 rounds per ship. Force is to retire from bombardment area by 080030 E Sep and return to present patrol area at full speed. One or two enemy frigates may be expected to encounter in the area in addition to enemy air threat”
The Commodore Commanding PN Flotilla accordingly originated his signal at 1835, the salient features of which were:
a. The initial position for attack was 206 degrees Dwarka light 6 miles
b. The target was to be city installations and conspicuous chimney
c. Complete radio silence was to be maintained except for guarding air warning radar.
The Fleet immediately topped up fuel and shaped course for Dwarka operation. At midnight the ships were on Initial Position (IP) with all their guns loaded and the men ready to strike a historic punch on enemy’s face. The city of Dwarka was completely blacked out and target could only be idengified on radar. At 0024 bombardment was ordered to commence when ships were 5.5 to 6.3 miles from Dwarka light. It took only four minutes to complete the bombardment, firing altogether about 350 rounds on the target. Upon successful completion of the attack the ships retired immediately without any loss or damages. There was no considerable resistance from the enemy and the ships safely arrived at their patrol area by 0635 on 8 Sep.
SUBMARINE OPERATION 1971
Submarine Operation 1971 is another achievement of Pakistan Navy. INS KHUKRI, the ship of the Squadron Commander of Indian 14th Frigate Sqn was sunk within two minutes after receiving a hit in the magazine where explosives were held. 18 Officers and 176 sailors including the Commanding Officer lost their lives. This came as a shattering blow to the Indian Navy.
During 1971 Indo-Pak war, the burden of Pakistan Navy’s offensive effort hinged on the small but effective submarine force. PN Submarine HANGOR sailed in the early hours of 22 November 1971 to patrol off the Indian Kathiawar coast under the command of Commander Ahmed Tasnim S.J.
On 9 Dec, in an effort to locate the evasive enemy, HANGOR extended her patrol northward to investigate some radio transmissions intercepted on her sensors. Two contacts were picked up on passive sonar and were identified as warships. The initial range was 6 to 8 miles. A pursuit of the enemy began but the first attempt to attack these ships failed due to speed disadvantage. The submarine however managed to forecast target ships movement and succeeded in taking up a tactically advantageous position on the path of the patrolling frigates by 1900. At 1957 the submarine fired a down the throat shot with a homing torpedo at the northerly ship from a depth of 40 meters.
The torpedo was tracked but no explosion was heard. The second torpedo was therefore fired immediately on the incoming southerly ship and this was followed by a tremendous explosion. The torpedo had found its mark. The other enemy frigate came straight for the submarine when a third torpedo was fired. A distant explosion was heard subsequently and the submarine turned west towards deeper waters for evasion.
In this spectacular action, INS KHUKRI, the ship of the Squadron Commander of Indian 14th Frigate Sqn was sunk within two minutes after receiving a hit in the magazine where explosives were held. This came as a shattering blow to the Indian Navy. HANGOR’s action demonstrated Pakistan Navy’s tactical superiority in sub-surface warfare and after the war even the BBC commentators praised Pakistan Naval effort. Considering the shape, size and age of the ships at its command, they said that the Pakistan Navy had acquitted itself well against the Indian Navy.
