Product Information

The missiles were named Martlets, after the mythical bird on the crest of McGill University, Canada who administered HARP.

This album was recorded and mixed by Travis Harrison at Serious Business Music, NY, and Stillwater River Lodge [9] Critical reception [ edit ] The HARP space gun sits on a massive concrete base inclined at 45 degrees, is mounted a navy BB turret GIRDER which allow a CRADLE elevation of almost 90 degrees. The 86‑caliber (118‑foot)-long barrel consists of two modified MK II tubes joined in a massive sleeve by bolted, mating flanges. Four tension bars running from both the breech and from the muzzle to a cruciform spreader midway on the sleeve maintain barrel alignment and prevent droop. Elevation is accomplished by 4 steel rods running from the lower rear portion of the cradle to a hydraulic cylinders located in the pit.

Anti-satellite systems have also been investigated by the Soviet Union, China and India, among others. For example, a famous 2007 anti-satellite test by China generated a huge cloud of space junk. In 2013, a shard of the destroyed satellite hit a Russian satellite and destroyed that, too. In a three-body or larger system, a gravity assist trajectory might be available such that a carefully aimed escape velocity projectile would have its trajectory modified by the gravitational fields of other bodies in the system such that the projectile would eventually return to orbit the initial planet using only the launch delta-v.

With three Mana Boosters from the Nebula armor's set bonus, mana will regenerate faster than the weapon can consume it.

It is good to be reminded of the journey of the project. However, sanitising the full facts, to present a respectable academic view of history – never quite work out in the long term. It is also true that lessons learn on our sojourn help us shape a better future. a b c d e "Project High Altitude Research Program (HARP) Cannons Launch Chemical Payloads Into Space".

Whatever the true reason behind the project it is a shame that what remains of the HARP guns is being allowed to rust away neglected and forgotten. HARP was a small but important part of our history. Maybe the Barbados National Trust will recognize this and organize a restoration program. In the meantime the HARP space guns are rusting away – all for the want of a bit of paint every few years and some energy to get out and market this piece of history. a b Murphy, Charles; Bull, Gerald (February 1967).

Due to its long wind-up time, it is much more efficient to use Mana Potions with this weapon instead of Mana Regeneration Potions. a b c d Lukasiewicz, Julius (April 1986).

The Laser Machinegun could be considered an upgrade to the Laser Rifle or the Heat Ray, which would make it the final weapon in the Space Gun series. However, in combat it is more similar to the likes of the Razorpine and Sky Fracture since its projectiles do not pierce.

Orbital weaponry is any weapon that is in orbit around a large body such as a planet or moon. As of December 2022, there are no known operative orbital weapons systems, but several nations have deployed orbital surveillance networks to observe other nations or armed forces. Several orbital weaponry systems were designed by the United States and the Soviet Union during the Cold War. During World War II Nazi Germany was also developing plans for an orbital weapon called the Sun gun, an orbital mirror that would have been used to focus and weaponize beams of sunlight. [4]The High Altitude Research Project (HARP) space gun was set up at Paragon just to the east of the runway of what was then Seawell Airport – the brainchild of Canadian ballistics scientist Dr. Gerald Bull and jointly funded by McGill University, Canada and the USA Army Research and Development Center. There are six or seven levels (depending on which version of the game is being played) that are split into four subsections, each with its own end-of-level boss. [7] [8] Between levels the story is explained and moved forward through the use of short animated cut-scenes [9] with text on the screen. Players can often choose their own path through the level by selecting a door or arrow using the gun. [2] Several of the home system versions feature light gun support; however, all of them allow the player to move a crosshair to target enemies. The multiplayer game is identical to the single-player experience, [6] but the Sega Master System, Commodore 64 and ZX Spectrum versions do not feature multiplayer. [10] Development and release [ edit ] On November 18, 1966, the HARP gun operated by BRL at Yuma Proving Ground launched an 84-kg Martlet 2 missile at 2,100m/s, sending it briefly into space and setting a world altitude record of 179km. This feat has remained the world altitude record for any fired projectile. [4] [16] [23] Closure [ edit ] Abandoned HARP gun in Barbados
