Given the question: Information: - The United States Armed Forces are the federal armed forces of the United States. They consist of the Army, Marine Corps, Navy, Air Force, and Coast Guard. The President of the United States is the military's overall head, and helps form military policy with the U.S. Department of Defense (DoD), a federal executive department, acting as the principal organ by which military policy is carried out. From the time of its inception, the military played a decisive role in the history of the United States. A sense of national unity and identity was forged as a result of victory in the First Barbary War and the Second Barbary War. Even so, the Founders were suspicious of a permanent military force. It played an important role in the American Civil War, where leading generals on both sides were picked from members of the United States military. Not until the outbreak of World WarII did a large standing army become officially established. The National Security Act of 1947, adopted following World WarII and during the Cold War's onset, created the modern U.S. military framework; the Act merged previously Cabinet-level Department of War and the Department of the Navy into the National Military Establishment (renamed the Department of Defense in 1949), headed by the Secretary of Defense; and created the Department of the Air Force and National Security Council. - Honeywell International Inc. is an American multinational conglomerate company that produces a variety of commercial and consumer products, engineering services and aerospace systems for a wide variety of customers, from private consumers to major corporations and governments. The company operates three business units, known as Strategic Business Units Honeywell Aerospace, Honeywell Automation and Control Solutions, and Honeywell Performance Materials and Technologies. - The United States Army (USA) is the largest branch of the United States Armed Forces and performs land-based military operations. It is one of the seven uniformed services of the United States and is designated as the Army of the United States in the United States Constitution, Article 2, Section 2, Clause 1 and United States Code, Title 10, Subtitle B, Chapter 301, Section 3001. As the largest and senior branch of the U.S. military, the modern U.S. Army has its roots in the Continental Army, which was formed (14 June 1775) to fight the American Revolutionary War (17751783)before the U.S. was established as a country. After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784, to replace the disbanded Continental Army. The United States Army considers itself descended from the Continental Army, and dates its institutional inception from the origin of that armed force in 1775. - A turboshaft engine is a form of gas turbine which is optimized to produce shaft power rather than jet thrust. - LHTEC (Light Helicopter Turbine Engine Company) is a joint venture between Rolls-Royce and Honeywell. The company was originally a partnership between the Allison Engine Company and AlliedSignal Aerospace. In 1995 Rolls-Royce acquired Allison, and AlliedSignal merged with Honeywell in 1999, and adopted its name. - The Light Helicopter Turbine Engine Company T800 is a turboshaft engine for rotary wing applications . It is produced by the LHTEC , a joint venture between Rolls - Royce and Honeywell . The commercial and export version is the CTS800 . The engine was primarily developed for the United States Army 's cancelled RAH - 66 Comanche armed reconnaissance helicopter , but has found use in other applications . - Honeywell Aerospace is a manufacturer of aircraft engines and avionics, as well as a producer of auxiliary power units (APUs) and other aviation products. Headquartered in Phoenix, Arizona, it is a division of the Honeywell International conglomerate. It generates approximately $10 billion in annual revenue from a 50/50 mix of commercial and defense contracts. - The Congress of the Confederation, or the Confederation Congress, formally referred to as the United States in Congress Assembled, was the governing body of the United States of America that existed from March 1, 1781, to March 4, 1789. It comprised delegates appointed by the legislatures or assemblies of the several states. It was preceded by the Second Continental Congress (17751781) and governed under the newly adopted "Articles of Confederation and Perpetual Union", which were proposed 17761777, adopted by the Continental Congress in July 1778 and finally agreed to by a unanimous vote of all thirteen states by 1781, held up by a long dispute over the cession of western territories beyond the Appalachian Mountains to the central government led by Maryland and a coalition of smaller states without western claims. The newly reorganized Congress at the time continued to refer itself as the Continental Congress throughout its eight-year history, although modern historians separate it from the earlier bodies, which operated under slightly different rules and procedures until the later part of American Revolutionary War. The membership of the Second Continental Congress automatically carried over to the Congress of the Confederation when the latter was created by the ratification of the Articles of Confederation. It had the same secretary as the Second Continental Congress, namely Charles Thomson. The Congress of the Confederation was succeeded by the Congress of the United States as provided for in the Constitution of the United States, proposed September 17, 1787, in Philadelphia and ratified by the states through 1787 to 1788 and even into 1789 and 1790. - The Continental Army was formed by the Second Continental Congress after the outbreak of the American Revolutionary War by the colonies that became the United States of America. Established by a resolution of the Congress on June 14, 1775, it was created to coordinate the military efforts of the Thirteen Colonies in their revolt against the rule of Great Britain. The Continental Army was supplemented by local militias and troops that remained under control of the individual states or were otherwise independent. General George Washington was the commander-in-chief of the army throughout the war. - AlliedSignal was an American aerospace, automotive and engineering company created through the 1985 merger of Allied Corp. and Signal Companies. It subsequently purchased Honeywell for $15 billion in 1999, and thereafter adopted the Honeywell name and identity. - Aerospace is the human effort in science, engineering and business to fly in the atmosphere of Earth (aeronautics) and surrounding space (astronautics). Aerospace organisations research, design, manufacture, operate, or maintain aircraft and/or spacecraft. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications. - The Code of Laws of the United States of America (variously abbreviated to Code of Laws of the United States, United States Code, U.S. Code, or U.S.C.) is the official compilation and codification of the general and permanent federal statutes of the United States. It contains 52 titles, and a further three titles have been proposed. The main edition is published every six years by the Office of the Law Revision Counsel of the House of Representatives, and cumulative supplements are published annually. The official version of those laws not codified in the United States Code can be found in United States Statutes at Large. - A gas turbine, also called a combustion turbine, is a type of internal combustion engine. It has an upstream rotating compressor coupled to a downstream turbine, and a combustion chamber in between. - The Allison Engine Company was an American aircraft engine manufacturer. Shortly after the death of James Allison in 1929 the company was purchased by the Fisher brothers. Fisher sold the company to General Motors, which owned it for most of its history. It was acquired by Rolls-Royce plc in 1995 to become a subsidiary, Rolls-Royce Corporation. - The Army of the United States or Armies of the United States is the legal name of the "land forces of the United States" (United States Constitution, Article 2, Section 2, Clause 1 and United States Code, Title 10, Subtitle B, Chapter 301, Section 3001) and has been used in this context since at least 1841, as in the title: "General Regulations for the Army of the United States". The Army, or Armies of the United States includes: the Regular Army, Army National Guard, and the Army Reserve, (as well as any volunteer or conscripted forces). - The American Revolutionary War (17751783), also referred to as the American War of Independence and the Revolutionary War in the United States, was an armed conflict between Great Britain and thirteen of its North American colonies that after onset of the war declared independence as the United States of America.
