SUBMARINE TASKING. Pursuant to mission accomplishment in support of national policies, and in particular for a duly delineated national armed-force objective to “Project National Power,” submarines can be tasked to launch land-attack cruise-missiles from international waters– as directed unilaterally by our National Command Authority, NCA.
Submarines can be tasked to conduct surveillance and reconnaissance operations inside and outside the battle space, covertly. In that same vein, submarines can be tasked to insert, and, or retract Special Operating Forces, SOF, on the littoral shores of the world’s oceans– covertly.
In more poignant warfare scenarios, submarines can be tasked to mine sea-lane choke points as well as enemy harbors.
Moreover, and perhaps most particular, submarines can hunt and kill other opposing submarines in the same undersea medium with them. Besides the deep ocean, that undersea medium includes the shallow waters for our coastal defense as well as that for projecting US national power by amphibious forces in foreign waters.
Notwithstanding the brassy jingoism above, submarines were first procured to sink threatening warships by surprising them from below the sea with the numbing sting of a torpedo. For over a hundred years now, submarines have been so tasked; and, since WWI, submarines have been tasked to interdict sea lanes and sink unarmed merchant ships to deny re-supply. Yes, VIRGINIA, an economic strangler lurks in the sea— Submarines Sink Ships!
When SEAWOLF— conceptualized in the painting above—was launched in 1995, there were some 24,000 merchant ships of over 1,000 gross-registered-tons plying the sea lanes of the world for international trade and transport. For national comparison, a table of Merchant Fleets of the World, ranked by number of oceangoing vessels, is provided below delineating a grand total of their displacements as about 657-million dwt (deadweight tons).
As capital-intensive assets—meaning their annual amortized construction cost and operating expense well exceed the cost of labor to operate them—their collective loan-value, without any consigned cargo, can be estimated parametrically to total about $1.5-trillion. Moreover, the annualized value of their consigned cargo that they deliver each year can be estimated to total about $3.0-trillion.
Ask yourself which of these national economies today could stay afloat with the sunk cost of its Merchant Fleet?
And today, with near instantaneous news around the world, when the first explosion from a submarine-launched torpedo plumes brusquely, so will ocean-shipping insurance rates.
In regard to fleet operations, submarines can be tasked to provide INDIRECT, ASSOCIATED, and DIRECT Battle Group support. For deployments, Time-On-Station for modern nuclear-powered submarines is dependent only on the amount of food they must carry to feed their crew—like, a 90-day supply, without replenishment.
Some submarine-patrol stations literally are On the Far Side. For instance, our forward submarine base on Guam in the western Pacific is about 12 days of submerged steaming from San Diego. Then for a submerged transit from Guam to a patrol station in the Gulf of Oman via the Java Sea and the Lombok Straits thence across the Indian Ocean could take as long as 16 days.

INDIA APPROVES $10.7BN SUBMARINE DEAL: The Indian Defence Ministry has approved a Rs500bn ($10.7bn) project to build six new-generation submarines for the Indian Navy. Under the program, which is codenamed Project-75 India (P-75I), all six diesel electric submarines will be built with air-independent propulsion systems and incorporate stealth, land-attack capability and a wide range of next-generation technologies, according to the Times of India. The request for proposal will be issued to global submarine manufacturers, including Rosoboronexport of Russia, DCNS/Armaris of France, HDW of Germany and Navantia of Spain. The construction cost for each of the six submarines will be around Rs85bn ($1.8bn). Three of the six submarines will be built at Mazagon Docks (MDL) in Mumbai. One will be built at Hindustan Shipyard in Visakhapatnam, in cooperation with a foreign company. The remaining two submarines are expected to be directly imported from the foreign collaborator or constructed at a private shipyard in India. The first submarine under P-75I is expected to be launched in six to seven years, according to a defence official. Currently, the Indian Navy operates an aging fleet of 15 diesel submarines.
