Other [two pens shaped like the B61 nuclear weapon with transporter]. Like new. When was the pen invented? If we only think about a pen as an instrument used for making marks on another surface, we must consider that the pen as being invented during the stone age. Over the centuries writing instruments have evolved into the pen as we know it. In May of 1827, France issued its first patent on the fountain pen to a Parisian Student, Romanian Petrache Poenaru. The fountain pen which features a fine stainless-steel tip, still needs an ink well to be constantly filled with ink. Widespread production of these customized pens taking another 30 years, with others improving on the filling techniques. Fountain pens become a favorite with professionals such as barristers, professors, doctors and accountants and remain a mainstay for over a century. Originally the concept of the ballpoint pen was proposed by John J. Loud, who was looking for a way to write on surfaces other than paper. The concept was simple enough, a thin tube of ink would be placed in a comfortable cylinder, the ink would be held in a metal ball in a socket. When the ball was pressed against a writing surface, the ball would rotate in the socket allowing a smooth even flow of ink. Mr. Loud receive his first patent for the ball point pen on October 30, 1888. Each innovation made the ballpoint better and cheaper to manufacturer. Ballpoint pens soon became available in every color, style, shape and design. They featured permanent ink, erasable ink, black ink, blue ink, red ink. It was the revolution of the pen. From Wikipedia: The B61 nuclear bomb is the primary thermonuclear gravity bomb in the United States Enduring Stockpile following the end of the Cold War. It is a low-to-intermediate yield strategic and tactical nuclear weapon featuring a two-stage radiation implosion design. The B61 is of the variable yield ("dial-a-yield" in informal military jargon) design with a yield of 0.3 to 340 kilotons in its various mods ("modifications"). It is a Full Fuzing Option (FUFO) weapon, meaning it is equipped with the full range of fuzing and delivery options, including air and ground burst fuzing, and free-fall, retarded free-fall and laydown delivery. It has a streamlined casing capable of withstanding supersonic flight and is 11 ft 8 in (3.56 m) long, with a diameter of about 13 inches (33 cm). Basic weight is about 700 pounds (320 kg), although the weights of individual weapons may vary depending on version and fuze/retardation configuration. As of 2020, it is undergoing a 12th modification. According to the Federation of American Scientists in 2012, the roughly 400 B61-12s will cost $28 million apiece. As of 2013 the Pentagon saw the B83 nuclear bomb as a "relic of the Cold War," believing that deploying a megaton-yield gravity bomb, the highest level nuclear weapon left in the U.S. inventory, to Europe was "inconceivable" at this point. It can also only be carried by the B-2 bomber, and integrating it onto additional aircraft would be costly. The Mod 12 upgrade is being pursued as a forward-deployed tactical/strategic nuclear weapon to protect NATO and Asian allies since it can be used from dual-capable fighter aircraft, as well as planned to arm the F-35 and B-21 Raider, and its lower yield options make it more flexible with less collateral effects. Recapitalizing the B61 is hoped to lead to the retirement of the B83, resulting in the elimination of the last megaton-yield U.S. bomb and leave the B61-series as the only U.S. gravity nuclear bomb. In 2013, the Pentagon and NNSA stated that if B61 refurbishment did not begin by 2019, components in the existing weapons could begin to fail. Initially, the NNSA Stockpile Stewardship and Management Plan anticipated Phase 1 development for the B61 Mod 13 Life Extension Program (LEP) beginning in 2037 with first production of the weapon in 2050, but in 2023 plans were announced to produce a new gravity bomb similar to that of the B61-12, but having a high yield similar to that of the B61-7, named the B61 Mod 13. This discards plans for the Mod 13 to be a future Mod 12 LEP. It is planned that for each B61-13 produced, one fewer B61-12 is to be produced, therefore not increasing the planned number of new B61 bombs; defense officials indicated only "a few dozen" B61-13s may be produced. The new bomb will be carried by the B-21 Raider, but it is not planned to be deployed on the F-35., 5, Paperback / softback. New.
