SSN(X)-class Submarine
The SSN(X) or Next-Generation Attack Submarine program of the United States Navy aims to develop a new class of nuclear-powered attack submarines to succeed the ''Virginia'' and '' Seawolf'' classes. The SSN(X) program remains in the early stages of development and no official details have been released about its design or capabilities. This program is expected to incorporate advanced technologies and capabilities to ensure that the new submarines will be able to meet the evolving challenges of the modern maritime environment. It is believed that the SSN(X) program will focus on improving stealth, sensor capabilities, and firepower to enable the new submarines to operate effectively in a variety of missions, including intelligence gathering, special operations, and anti-submarine warfare. Along with the ballistic missile submarine, the SSN(X) program is seen as a critical component of the Navy's future submarine force and is expected to play a key role in maintaining American n ...

General Dynamics Electric Boat
General Dynamics Electric Boat (GDEB) is a subsidiary of General Dynamics Corporation. It has been the primary builder of submarines for the United States Navy for more than 100 years. The company's main facilities are a shipyard in Groton, Connecticut, a hull-fabrication and outfitting facility in Quonset Point, Rhode Island, and a design and engineering facility in New London, Connecticut. History The company was founded in 1899 by Isaac Rice as the Electric Boat Company to build John Philip Holland's submersible ship designs, which were developed at Lewis Nixon's Crescent Shipyard in Elizabeth, New Jersey. ''Holland VI'' was the first submarine that this shipyard built, which became when it was commissioned into the United States Navy on April 11, 1900—the first submarine to be officially commissioned. The success of ''Holland VI'' created a demand for follow-up models (A class or ) that began with the prototype submersible ''Fulton'' built at Electric Boat. Some f ...

Unmanned Aerial Vehicle
An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs are a component of an unmanned aircraft system (UAS), which includes adding a ground-based controller and a system of communications with the UAV. The flight of UAVs may operate under remote control by a human operator, as remotely-piloted aircraft (RPA), or with various degrees of autonomy, such as autopilot assistance, up to fully autonomous aircraft that have no provision for human intervention. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications.Hu, J.; Bhowmick, P.; Jang, I.; Arvin, F.; Lanzon, A.,A Decentralized Cluster Formation Containment Framework for Multirobot Systems IEEE T ...

SSN-AUKUS
The SSN-AUKUS, also known as the SSN-A, is a planned class of nuclear-powered fleet submarine (SSN) intended to enter service with the United Kingdom's Royal Navy in the late 2030s and Royal Australian Navy in the 2040s. The class will replace the UK's and Australia's submarines. The UK commenced an ''Astute'' class replacement project in 2018, which was later named the Submersible Ship Nuclear Replacement (SSNR). The ongoing SSNR design was renamed SSN-AUKUS in March 2023, under the 2021 AUKUS trilateral security partnership, when Australia joined the programme and additional US technology was incorporated into the design. Australia plans to build five SSN-AUKUS submarines in addition to acquiring three nuclear-powered submarines from the United States. The class will be powered by Rolls-Royce's pressurised water reactors (PWR). Development UK SSNR The United Kingdom began planning for the replacement of the ''Astute'' class of submarines in early 2018. Initially, the ...

DDG(X)
The DDG(X) program, also known as the Next-Generation Guided-Missile Destroyer program, is a United States Navy program to develop a class of surface combatant vessels to succeed its 22 Flight II s and 27 Flight I/II s. The program is the culmination of the Large Surface Combatant (LSC) initiative that followed the cancellation of CG(X) and curtailing of the procurement of the . The ships will become the principal large surface combatants of the U.S. Navy; compared to their predecessors, they will incorporate more powerful sensors and have more room and weight margin for growth. History With the cancellation of the CG(X) in 2010, the U.S. Navy embarked on new studies and programs for the future of the air defense role fulfilled by the ''Ticonderoga''-class cruisers. Because the cruisers were built on the ''Spruance''-class destroyer hulls, they had limited upgrade potential due to space, weight, and power margins. Meanwhile, the procurement of the ''Zumwalt''-class destroyers wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Constellation-class Frigate
The ''Constellation'' class is a class of multi-mission guided-missile frigates under development for the United States Navy as a follow-on to the modular littoral combat ship. The U.S. Navy announced the FFG(X) frigate project in the United States Department of Defense Request For Information (RFI) on 10 July 2017. The U.S. Navy selected five shipbuilders to evolve their designs into a prospective design for the proposed twenty FFG(X) guided-missile frigates. On 30 April 2020, it was announced that Fincantieri Marinette Marine had won the contract with its FREMM multipurpose frigate-based design. The project was later renamed FFG-62 program after the lead ship was named. Development The U.S. Navy procured the first FFG 62 in FY2020, the next was awarded in April 2021, and the third is planned to be awarded is FY22. The U.S. Navy's proposed FY2020 budget request was $1.281 billion for the procurement of the first FFG 62. The U.S. Navy's FY2020 budget submission shows that ...

CG(X)
The CG(X) program, also known as the Next Generation Cruiser program, was a United States Navy research program to develop a replacement vessel for its 22 s. Original plans were for 18–19 ships, based on the 14,500 ton with additional ballistic missile defense and area air defense for a carrier group. These vessels were to enter service beginning in 2017. The program was ended in 2010 with its mission to be fulfilled by the successor to the Flight III ''Arleigh Burke''–class destroyers. History Background In the early 1990s, the U.S. Armed Forces had to respond to new threats and budgets after the end of the Cold War. The U.S. Navy's response was the Surface Combatant for the 21st Century (SC-21) program. This envisaged a destroyer called DD-21 and a planned cruiser called CG-21. Budget cuts in November 2001 meant that SC-21 became the less ambitious Future Surface Combatant program. The DD-21 was renamed DD(X), which was later named the destroyer. By April 2002, DD( ...

Cruiser Baseline
The cruiser baseline (CGBL) was a design study for a ship that has the combat capabilities of VLS-capable (CG-52 onwards) while designing the hull to DDG-51 () standards and technology. The resulting design was considerably larger than the ''Ticonderoga''-class design, owing to increased margins and allowances for weight and mission growth.

Ballistic Missile Submarine
A ballistic missile submarine is a submarine capable of deploying submarine-launched ballistic missiles (SLBMs) with nuclear warheads. The United States Navy's hull classification symbols for ballistic missile submarines are SSB and SSBN – the ''SS'' denotes submarine, the ''B'' denotes ballistic missile, and the ''N'' denotes that the submarine is nuclear powered. These submarines became a major weapon system in the Cold War because of their nuclear deterrence capability. They can fire missiles thousands of kilometers from their targets, and acoustic quieting makes them difficult to detect (see acoustic signature), thus making them a survivable deterrent in the event of a first strike and a key element of the mutual assured destruction policy of nuclear deterrence. The deployment of SSBNs is dominated by the United States and Russia (following the collapse of the Soviet Union). Smaller numbers are in service with France, the United Kingdom, China and India; North Ko ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

A hundred years before it was established, the Niantic people settled in the area between the Thames River and Pawcatuck River, but they eventually settled in Westerly, Rhode Island. The newcomers to the land were the Pequots, a branch of the Mohawk people who moved eastward into the Connecticut River Valley. The summer of 1614 was the first time that the Pequots encountered whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Congressional Budget Office
The Congressional Budget Office (CBO) is a federal agency within the legislative branch of the United States government that provides budget and economic information to Congress. Inspired by California's Legislative Analyst's Office that manages the state budget in a strictly nonpartisan fashion, the CBO was created as a nonpartisan agency by the Congressional Budget and Impoundment Control Act of 1974. Whereas politicians on both sides of the aisle have criticized the CBO when its estimates have been politically inconvenient, economists and other academics overwhelmingly reject that the CBO is partisan or that it fails to produce credible forecasts. There is a consensus among economists that "adjusting for legal restrictions on what the CBO can assume about future legislation and events, the CBO has historically issued credible forecasts of the effects of both Democratic and Republican legislative proposals."
