The '''battleship''', though now essentially obsolete as a naval weapon, is a naval vessel intended to engage the most powerful warships of an opposing navy. Evolved from the [[ship of the line]], their main armament consisted of multiple heavy [[cannon]] mounted in movable [[turret]]s. The ships boasted extensive armor and as such were designed to survive severe punishment inflicted upon them by other capital ships.
 
The word "battleship" was coined around 1794 and is a contraction of the phrase "line-of-battle ship," the dominant wooden warship during the [[Age of Sail]].<ref name="OED">"battleship" The Oxford English Dictionary. 2nd ed. 1989.

Subsequent battleship designs were therefore referred to as "dreadnoughts." A general criterion from thereon in was that the armor of a true battleship must be sufficiently thick to withstand a hit by its own most powerful gun, within certain constraints.

From 1905 to the early 1940s, battleships defined the strength of a first-class navy.  The idea of a strong "fleet in being", backed by a major industrial infrastructure, was key to the thinking of the naval strategist per [[Alfred Thayer Mahan]], writing in his 1890 book, ''The Influence of Sea Power upon History, 1660-1763'' (1890). The essence of Mahan from a naval viewpoint is that a great navy is a mark and prerequisite of national greatness. In a 1912 letter to the ''New York Times'', he counseled against relying on international relations for peace, and pointed out that other major nations were all building battleships.<ref>{{citation

The Irvin pin. The eyes have always been red, but there are urban legends about the meanings of other colors.
A pin from another company, possibly Switlik or Standard Parachute. This style is common in catalogs and auctions of military memorabilia.

The Caterpillar Club is an informal association of people who have successfully used a parachute to bail out of a disabled aircraft. After authentication by the parachute maker, applicants receive a membership certificate and a distinctive lapel pin.

History

Before April 28, 1919 there was no way for a pilot to jump out of a plane and then to deploy a parachute. Parachutes were stored in a canister attached to the aircraft, and if the plane was spinning, the parachute could not deploy. Film industry stuntman Leslie Irvin developed a parachute that the pilot could deploy at will from a back pack using a ripcord. He joined the Army Air Corps parachute research team, and in April 1919 he successfully tested his design, though he broke his ankle during the test. Irvin was the first person to make a premeditated free fall jump from an airplane. He went on to form the Irving Airchute Company, which became a large supplier of parachutes. (A clerical error resulted in the addition of the "g" to Irvin and this was left in place until 1970, when the company was unified under the title Irvin Industries Incorporated.) The Irvin brand is now a part of Airborne Systems, a company with operations in Canada, the U.S. and the U.K.[1].

An early brochure [2] of the Irvin Parachute Company credits William O'Connor 24 August 1920 at McCook Field near Dayton, Ohio as the first person to be saved by an Irvin parachute, but this feat was unrecognised. On 20 October 1922 Lieutenant Harold R. Harris, chief of the McCook Field Flying Station, jumped from a disabled Loening W-2A monoplane fighter. Shortly after, two reporters from the Dayton Herald, realising that there would be more jumps in future, suggested that a club should be formed. 'Caterpillar Club' was suggested because the parachute canopy was made of silk, and because caterpillars have to climb out of their cocoons and fly away. Harris became the first member, and from that time forward any person who jumped from a disabled aircraft with a parachute became a member of the Caterpillar Club. Other famous members include General James Doolittle, Charles Lindbergh and (retired) astronaut John Glenn.

In 1922 Leslie Irvin agreed to give a gold pin to every person whose life was saved by one of his parachutes. By 1945 the number of members with the Irvin pins had grown to over 34,000. In addition to the Irvin Air Chute Company and its successors, other parachute manufacturers have also issued caterpillar pins for successful jumps. Irvin/Irving's successor, Airborne Systems Canada, still provides pins to people who made their jump long ago and are just now applying for membership. Another of these is Switlik Parachute Company, which though it no longer makes parachutes, still issues pins.
