What?? I hope you don't mean U.S. Navy submarines as they can't go much lower than 1000 feet. This whole Oil thing is taking place at 5000-6000feet.
No military submarine can go that far not even the Russian ones which have the world record for deepest drives

But Not The BIG Boats
Deep Submergence VehicleDeep Submergence Vehicle
A Deep Submergence Vehicle (DSV) is a deep diving manned submarines that is self-propelled. The term DSV is generally one used by the United States
, though several navies operate vehicles that can be accurately described as DSVs. DSVs are commonly divided into two types: research DSVs,
which are used for exploration and surveying, and DSRVs (Deep Submergence Rescue Vehicle), which can be used for rescuing the crew of a sunken
submarine and/or clandestine (espionage) missions (primarily installing wiretaps on undersea cables). DSRV type vessels are equipped with docking
chambers to allow personnel ingress/egress via a manhole.
The real-life feasibility of any DSRV-based rescue attempt is hotly debated, because the few available docking chambers of a stricken submarine may be
flooded, trapping the sailors still alive in other dry compartments. Because of these difficulties, the use of integrated crew escape capsules and/or
detachable conning tower has gained favour in military submarine design during the last two decades and most DSRV are now primarily relegated to
clandestine missions and undersea military equipment maintenance, if at all. The rapid development of safe, cost-saving ROV technology has also
rendered some DSV vessels obsolete.
Strictly speaking bathyscaphes are not submarines because they have minimal mobility and are built like a balloon, using a habitable spherical
pressure vessel hung under a liquid hydrocarbon filled float drum. In a DSV/DSRV type vehicle the passenger compartment and the ballast tank
functionality is incorporated into a single structure to afford more habitable space (up to 24 people in the case of a DSRV rescue vehicle).
Most DSV/DSRV vehicles are powered by traditional electric battery propulsion and have very limited endurance. Plans have been made to equip DSVs with
closed circuit internal combustion powerplants (LOX Stirling engines) but none have been realized so far, due to cost and maintenance considerations.
All DSV vehicles are dependent upon a surface support ship or a mother submarine, that can piggyback or tow them (in case of the NR-1) to the scene of
operations. Some DSRV vessels are air transportable in very large military cargo planes to speed up deployment in case of emergency rescue
List of Deep Submergence Vehicles
Trieste class bathyscaphe
* FNRS-2 - the predecessor to Trieste
* DSV-0 Trieste — the X-1 Trieste bathyscaphe has reached Challenger Deep, the world's deepest seabed. It was retired in 1966.
* DSV-1 X-2 Trieste II — an updated bathyscathe (or bathyscaph) design, participated in clandestine missions, it was retired in 1984.
* Bathyscaphe Archimede — French-made bathyscaphe, operated around the time of the Trieste.
Alvin class submarine
Alvin, owned by the Office of Naval Research (ONR) is operated under agreement by the National Deep Submergence Facility at the Woods Hole
Oceanographic Institution (WHOI), where it conducts science oriented missions funded by the National Science Foundation (NSF), National Oceanic and
Atmospheric Administration (NOAA) and ONR. Alvin has a maximum depth capability of 4500 meters
and operates from R/V Atlantis, an AGOR-23 class
vessel owned by the ONR and operated by WHOI under a charter party agreement. The NSF has committed to the construction of a replacement sub with
enhanced capabilities and 6500 meter
depth capability to replace Alvin, which will be retired upon its completion.
