<P> The presence of nuclear weapons on board U.S. aircraft carriers since the end of the Cold War has neither been confirmed nor denied by the U.S. government . As a result of this, the presence of a U.S. aircraft carrier in a foreign port has occasionally provoked protest from local people, for example when USS Nimitz docked in Chennai, India, in 2007 . At that time, the Strike Group commander Rear Admiral John Terence Blake stated that: "The U.S. policy is that we do not routinely deploy nuclear weapons on board Nimitz ." </P> <P> In May 2013, George H.W. Bush conducted the first carrier - borne end - to - end at - sea test of the Surface Ship Torpedo Defense System (SSTDS). The SSTDS combines the passive detection of the Torpedo Warning System (TWS) that finds, classifies, and tracks torpedoes with the hard - kill capability of a Countermeasure Anti-Torpedo (CAT), an encapsulated miniature torpedo designed to locate, home in on, and destroy hostile torpedoes . This increases protection against wake - homing torpedoes like the Type 53 that don't respond to acoustic decoys . The pieces of the SSTDS are engineered to locate and destroy incoming torpedoes in a matter of seconds . Each system includes one TWS and 8 CATs . Initial operational capability (IOC) is planned for 2019 and all aircraft carriers are to be outfitted by 2035 . </P> <P> In order for a carrier to deploy, it must embark one of ten Carrier Air Wings (CVW). The carriers can accommodate a maximum of 130 F / A-18 Hornets or 85--90 aircraft of different types, but current numbers are typically 64 aircraft . Although the air wings are integrated with the operation of the carriers they are deployed to, they are nevertheless regarded as a separate entity . As well as the aircrew, the air wings are also made up of support personnel involved in roles including maintenance, aircraft and ordnance handling and emergency procedures . Each person on the flight deck wears color - coded clothing to make his role easily identifiable . </P> <P> A typical carrier air wing can include 24--36 F / A-18E or F Super Hornets as strike fighters; two squadrons of 10--12 F / A-18C Hornets, with one of these often provided by the U.S. Marine Corps (VMFA), also as strike fighters; 4--6 EA - 18G Growlers for electronic warfare; 4--6 E-2C or D Hawkeyes for airborne early warning (AEW), C - 2 Greyhounds used for logistics (to be replaced by MV - 22 Ospreys); and a Helicopter Antisubmarine Squadron of 6--8 SH - 60F and HH - 60H Seahawks . Aircraft that have previously operated from Nimitz - class carriers include F - 4 Phantoms, RA - 5C Vigilantes, RF - 8G Crusaders, F - 14 Tomcats, S - 3 Vikings, EA - 6B Prowlers, A-7 Corsair II and A-6E Intruder aircraft . </P>
