The most visible difference between the HH-53B and HH-53C was that the HH-53C dispensed with the fuel-tank bracing struts. Experience with the HH-53B showed that the original tank was too big, adversely affecting performance when they were fully fueled, and so a smaller 450 US gal (1,703 L) tank was adopted in its place. Other changes included more armor and a more comprehensive suite of radios to improve communications with C-130 tankers, attack aircraft supporting CSAR actions, and aircrews awaiting rescue on the ground. The HH-53C was otherwise much like the HH-53B, with the more powerful T64-GE-7 engines.<sup id="cite_ref-Vectorsite_6-2" class="reference"><a href="#cite_note-Vectorsite-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> </p> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:HH-53C_over_Vietnam_October_1972.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/b/b1/HH-53C_over_Vietnam_October_1972.jpg/220px-HH-53C_over_Vietnam_October_1972.jpg" decoding="async" width="220" height="176" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/b/b1/HH-53C_over_Vietnam_October_1972.jpg/330px-HH-53C_over_Vietnam_October_1972.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/b/b1/HH-53C_over_Vietnam_October_1972.jpg/440px-HH-53C_over_Vietnam_October_1972.jpg 2x" data-file-width="2021" data-file-height="1613" /></a><figcaption>A HH-53 seen from the gunner's position of a helicopter over Vietnam in October 1972</figcaption></figure> <p>A total of 44 HH-53Cs were built, with introduction to service in August 1968.

As with the HH-53B, the HH-53C was also used for covert operations and snagging reentry capsules, as well as snagging reconnaissance drones. A few were assigned to support the Apollo space program, standing by to recover an <a href="/wiki/Apollo_program" title="Apollo program">Apollo</a> <a href="/wiki/Apollo_Command/Service_Module" class="mw-redirect" title="Apollo Command/Service Module">capsule</a> in case of a launchpad abort, though such an accident never happened.<sup id="cite_ref-Vectorsite_6-3" class="reference"><a href="#cite_note-Vectorsite-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> </p><p>In addition to the HH-53Cs, the Air Force obtained 20 <b>CH-53C</b> helicopters for more general transport work.
