To achieve the low acoustic signature, Virginia incorporates newly designed anechoic coatings, isolated deck structures and a new design of propulsor. Virginia has two mast-mounted Raytheon submarine high data rate sub HDR multiband satellite communications systems that enable simultaneous communication at a super-high frequency SHF and extremely high frequency EHF. The Virginia-Class attack submarine is equipped with 12 vertical missile launch tubes and four mm torpedo tubes.
The vertical launching system has the capacity to launch 16 Tomahawk submarine-launched cruise missiles SLCM in a single salvo. There is a capacity for up to 26 mk48 ADCAP mod 6 heavyweight torpedoes and sub harpoon anti-ship missiles to be fired from the 21in torpedo tubes. The original contract that was awarded in December was for nine boats with an option for a tenth.
Nasdaq reported that General Dynamics has substantially reduced the cost as well as the delivery time of the Virginia- class boats from eighty-four to just sixty-six months, while also improving mission capability and ship construction quality. The defense contractor is also one of only two companies in the world that is equipped to build nuclear-powered submarines, and as such General Dynamics has enjoyed a dominant position as a navy contractor.
The United States Navy has been focused on strengthening its naval power by upgrading its fleet of missile submarines in response to potential threats from near-peer adversaries including China. The Virginia -class nuclear-powered cruise missile attack submarines were introduced in the mids as a replacement to the Cold War-era Los Angeles -class submarine line, thirty of which have already been retired.
The Block V submarines feature the VPM, an foot section of the boat that will serve as an undersea vertical launcher for missiles. The boats can also host the new version of the anti-ship Maritime Strike Tomahawk , a part of the Block V upgrade that will begin being delivered to the service later this month.

These submarines are powered by the S9G pressurized water reactor, two turbine engines with one shaft and pumpjet propulsor. It is worth mentioning that nuclear reactor was designed to last as long as the submarine. It will run for 33 years without refueling.
Submarines of this class are fitted with with multi-band satellite communication system. In the US Navy ordered a new batch of 9 Virginia class submarines in order to counter a threat posed by the growing China's Navy. Eight of these boats will be built to improved Block V standard. These will be larger and will carry more weapons. The Block V will have surfaced displacement of 10 t, opposed to 7 t of the current boats, and will be m long, while current boats are m long.
These new boats will carry up to 40 Tomahawk cruise missiles. The new boats will replace in service some older Los Angeles class boats. It is planned that deliveries will begin in and will be completed in Rickover SSN ? Can't find what you're looking for?
