Boing-Boing was the code-name for a type of capital-ship-killing missile designed and used by the Gudersnipe Foundation. It is remembered as one of the most devastating weapons of all time, and the only one retired for political reasons.
The Boing-Boing was officially known as the Excalibur Missile, though this name was seldom used. Boing-Boing was the most common and least colorful of its names. Throughout its survice history, the Boing-Boing maintained a perfect 100% 1-hit-kill rating. Whenever the missile successfuly struck a ship, it destroyed it.
Originaly built in the early Golden Age, Boing-Boings were used extensively into the Second Age. As the Alliance solidified, the Space Comission called for an international ban on the weapon. Though they listed all sorts of reasons, the fact of the matter was that the Boing-Boing was too effective a weapon, and no one else ould level the playing field.
Though this was exactly the sort of design that Gudersnipe attempted to achieve in all its weapons, in a rare show of diplomacy, the Foundation declared that all Boing-Boing missiles were to be removed from active warships and dismantled by A.Y. 2293.
Secretly, the weapons were taken to a storage facility and maintained in pristine condition for the next 3907 years.
In A.Y. 6200, approximately 103 years into the Kamian Succession Wars, the remaining Boing-Boings, still in perfect working order, were deployed at the Battle of Lerner Fields. Though the region would later be lost, the missiles had brought the Foundation a rare strategic victory, and Boing-Boing would return to production for the rest of the war.
The Boing-Boing barely qualifies as a missile at all, and had to be launched from a fighter-carrier using the magnetic catapults designed for launching starfighters. At 270 feet long and nearly 150 wide, it was a Behemoth of a weapon. Specifically designed for "one hit, one kill", it was larger than any conventional missile or torpedo ever constructed for space-to-space use.
Propulsion came from an external plasma pulsed propulsion system, essentially a large metal pusher plate on shock absorbers. The fuel was antimatter-catalyzed N1 devices, jettisoned behind the missile and detonated, launching a wave of plasma that struck the pusher plate and moved it forward.
This method was the reason of the weapon's immense sise, and gave the missile a top speed of 80PSL. Though equivalant to the energetic plasma motors employed on standard missiles, the Boing-Boing could carry a larger quantity of fuel, giving it enough delta-V to hange its speed by 40PSL.
Conventional missiles launched from a capital ship only had enough delta-V to change speed by about 10PSL. Meaning the ship's flank speed of 40PSL combined with the rocket's delta-V results in a top speed of only 50PSL. A Boing-Boing fired from a carrier has the ability to reach 80PSL.
The Boing-Boing's large size allowed it to carry a full targeting system, making it completely independent from the ship once fired. Conventional weapons typically must rely on sensor information from the firing warship for target accuisition and guidance. The Boing-Boing could be fired without a target, lock onto one, and attack with data from its own sensors.
Boing-Boings were equipped with a sophisticated shield frequency modulator. Most ships employed rotating shield frequncies to prevent such systems, but the Boing-Boing's onboard sensor grid allowed it to lock onto the current shield frequency a fraction of a second before impact, a feat not possible with a modulator relying on sensor data from the warship that fired it.
In addition to detonating any unspent fuel capsules, the Boing-Boing's primary payload was a one gigaton N1.5 device, located just forward of the fuel storage and immediately aft of the impactor. The sensor grid was located in a ring around the payload.
The payload was a 2-stage device with a 96-point implosion trigger, the fuel was Lithium Deuteride with a Lithium 7 isotope. Weighing nearly 1000 tons by itself, the payload was among the largest tactically deployed nuclear weapons ever constructed.
Forming the nose cone and part of the fuselage was a massive solid impactor. This was the Boing-Boing's true weapon, weighing nearly 1500 tons. The outer layer of the impactor, like the rest of Boing-Boing's skin, was covered in stainless steel. Beneath the steel was a layer of concrete (designed to cushion the impact), and the bulk of the core was a massive plug of solid natural uranium.
The impactor, traveling at close to 80% of the speed of light, was able to smash through any armor like tissue paper, allowing the bomb itself to detonate inside the ship's hull, ensuring a kill on even the largest warship.
Though not always successful, the impactor was also designed to act as a tertiary stage to the the main payload, boosting its yield by up to 70%, to 1.7 gigatons.
