tnx , I know all this
but there are some rumors about these destroyers , that Pakistan bought them and they entered PN
even some people claim that they've seen them in Pakistan many years ago
which I believe they've mistaken babr and palang with PNS Nazim ...
by the way , tnx again
That would seem likely. The Nazim is a Gearing class destroyer. The Iranian ships are Allen M Sumner class destoyers. Both types are very similar to begin with.
From the Sumner-class was spawned the Gearing-class.
In simple words, the Gearing-class was just a long-hull version of the Sumner-class. As can be seen from the picture above, the "hull plug" as it was known, was built between the two funnels. The reason: give the ships longer legs by giving them the opportunity to embark more fuel. The Gearing-class, because of its larger displacement lost some speed, compensated by an extra 1,000 nautical mile-range. Secondary armament was slightly reduced
Nazim is the former USS
Wiltsie (DD-716). In November 1961 she underwent
Fleet Rehabilitation and Modernization (FRAM) alterations. She received an enclosed bridge; a helicopter hangar and landing platform; triple-mounted Mk. 32 torpedo tubes; an ASROC launcher; and late model radar and sonar. She also received many improvements in accommodations for both officers and enlisted men.
The FRAM MK I program was designed primarily for the
Gearing-class destroyers. This upgrade included rebuilding the ship's superstructure, engines, electronic systems, radar, sonar, and weapons. The second twin 5" gun mount and all previous AA guns and ASW equipment were removed. Upgraded systems included
SQS-23 sonar,
SPS-10 surface search radar, 2 × triple
Mark 32 torpedo tubes, 8-cell Anti-Submarine Rocket (
ASROC) box launcher, and one
QH-50C DASH ASW drone helicopter, with its own landing pad and
hangar. Both the Mk 32 torpedo tubes and ASROC launched
Mk 44 homing ASW torpedoes.
Gearing class destroyers before and after FRAM modernization
The very similar FRAM MK II program was designed primarily for the
Sumner class destroyers, but was used to upgrade the
Gearing class as well. This upgrade program included life-extension refurbishment, a new radar system, ASROC (not fitted on the
Sumners), Mk. 32 torpedo tubes, DASH ASW drone, and most importantly, a new
variable depth sonar (VDS).

The similarities in configuration after FRAM are Obvious. Still, some equally Obvious differences: VDS or not, ASROC or not, B-Turret or not.
