Germany was the first country to use gas, chlorine in particular, in world war one. it was first used against British and French units in the first battle of Ypres.
The first country to use the tank was the inventors, the British, in world war one, though during the war the french and Germans made designs too
During WW 1, submarines played a major part of a major war for the first time. The role of a submarine was basically to use torpedoes to sink enemy warships and cargo vessels.
The first country to use nuclear power for electricity generation was the United States. The world's first commercial nuclear power plant, the Shippingport Atomic Power Station, began operation in 1958 in Pennsylvania. This marked a significant milestone in the development of nuclear energy as a source of power.
The first country to use the Lend-Lease Act was Britain, and the Soviet Union soon after.
The first country to successfully use a submarine in battle was the United States during the American Civil War. The Confederate submarine known as the H.L. Hunley made history on February 17, 1864, when it sank the USS Housatonic off the coast of Charleston, South Carolina. This marked the first time a submarine had engaged and destroyed an enemy warship in combat.
No - the Turtle was invented during the Revolutionary War, and as such, the United States as a country (and patents) did not exist at that time. The first submarine to use patented designs was the SS-1, the U.S. Navy's first Diesel-Electric submarine, designed and built by John P. Holland.

The first documented use of sonar was during World War I by the British Royal Navy to detect submarines. The technology was further developed during World War II for anti-submarine warfare.
The airplane, the submarine, the machine gun saw its first real widespread use, chemical weapons, flamethrowers.
The first country to use submarines operationally was the United States during the American Revolutionary War. The submersible vessel, known as the Turtle, was designed by David Bushnell in 1775 and attempted to attach explosive charges to British ships. Though it had limited success, the Turtle represents the earliest recorded use of a submarine in military operations.
The first submarine to use raft-mounted machinery was the USS Holland (SS-1). Commissioned in 1900, the Holland was notable for its innovative design, which included a separate machinery compartment mounted on a flexible raft. This design helped reduce vibration and noise, enhancing the submarine's stealth capabilities. The use of raft-mounted machinery became an important feature in future submarine designs.
