The Spectre SMG was developed by Italian company SITES in the mid-1980s. Spectre was designed primarily for close combat, anti-terror or police operations that require compact size, instant firepower at the short ranges and safety of operations.

Spectre is a recoil operated, automatic firearm. It fires from the closed bolt, an is a hammer-fired. The trigger group is more similar to handguns, than to SMG - it is Double Action without manual safety but with decocker. So, Spectre could be carried with loaded chamber and hammer down and then fired immediately simply by pressing the trigger. The receiver of the Spectre is made from stamped steel. The bolt is so designed that it acts as an air pump to push air through barrel shroud and provide aditional cooling for the barrel and action (very useful when firing long bursts). Spectre has top-folding stock and polymer forward handle. It uses high-capacity, four column magazines for increased firepower.

The development of the G11 rifle was started in the late 1960's, when West German government decided to replace existing G3 rifle with lighter weapon with much better hit probability.

The initial studies lead to the idea of the small-caliber, rapid-fire rifle that fires caseless ammunition. To ensure sufficient stopping/killing power for small-caliber bullets used, the rifle should had have the three-round bursts capability and high capacity magazine.

The new design, called G11, was created by german company Hecler und Koch, with the Dynamit Nobel company in team. The HK was responsible for the rifle itself, while Dynamit Nobel had to develop caseless ammunition.

The basic concept of the G11 is as follows:
The rifle features unique cylinder breech/chamber system that rotates 90 degrees. The cartridges in the magazine are located above the barrel, bullets down. Prior to each shot, first cartridge is pushed down from magazine into chamber and then breech/chamber rotates 90 degrees to align the cartridge with the barrel (see pic). After that, the cartridge is fired and the breech/chamber rotates back, ready for the next cartridge to be chambered. In the case of the cartridge ignition failure, the failed cartridge is pushed down from the chamber by the next cartridge. The breech can be manually "cocked" by the rotating handle at the side of the rifle, located beyond the pistol handle. The cocking handle does not move when gun is fired. Another interesting detail is that barrel, rotating breech, feed module and magazine are mounted in the housing that can move in the rifle back and forth. When firing single shots, the housing moves back and forward after the each shot. When firing the full-auto, the housing moves back and forward during each shot, resulting in moderate rate of fire of some 600 round per minute. But, when firing the three-round bursts, second and third cartridges are feed and fired as soon as the chamber is ready for it, and third bullet leaves the barrel PRIOR to the moment when the housing becomes to its rearward position. This results in very high rate of fire with three-shots bursts - ca. 2000 rounds per minute. Also, this results in that the actual recoil affects the rifle AFTER the last bullet in the burst is fired.

Rifle featured built-in 1X optical sight with simple circle aiming reticle. Early prototypes featured one 50 rounds polymer magazine, while latest versions featured 45 rounds magazines - one in the loaded position within the movable housing and two spare magazines on the top of the rifle, asides from the loaded magazine.

The caseless ammunition in its early appearance was designed as a block of the propellant, coated with flammable laquer, with bullet and primer "glued on" the propellant. Final ammunition design DM11, that appeared in the mid-1980s, featured "telescopic" design, when bullet was fully enclosed in the block of the propellant. The cartridge propelled the bullet that weights 3.25 gramms, to the 930-960 meters per second.

Early prototypes were prone to the ammunition cook-offs during the sustained fire, but later Dynamit Nobel solved this issue.

In the late 1980s the Bundeswehr (West German Army) began the field tests of the pre-production G11s. After the initial tests, some improvements were devised, such as removable optical sight, mounting of two spare magazines on the rifle, and bayonet/bipod mount under the muzzle.

The modified variant, called G11K2, was tested in 1989, scoring at least 50% better combat accuracy when compared to G3 rifle. Initial batch of some 1000 G11K2s was received by Bundeswehr in 1990 or so, but due to some reasons the whole programme was cancelled by German Government. Main reasons of this cancellation were, in my opinion, the lack of fundings after the re-union of the West and East Germanies, and the general NATO policy for unification of the ammunition and even magazines for the assault rifles.

The slightly modified G11 was also tested in the USA under the ACR (Advanced Cobat Rifle) programme, in 1990. The ACR programme was not intended to result in adoption of the new rifle for the US Army, just to test new technologies and designs, and the G11 proved itself as a very accurate, comfortable to handle and fire, and reliable weapon.

FN P90 (Belgium)

Caliber: 5.7x28mm SS190
Weight: 2.54 kg empty; 3 kg loaded with magazine with 50 rounds
Lenght: 500 mm
Barrel lenght: 263 mm
Rate of fire: 900 rounds per minute
Magazine capacity: 50 rounds
Effective range: 200 meters

The FN P90 submachine gun (SMG) was developed in the late 1980s as a defensive weapon for the troops whose primary activities does not include small arms - vehicle and tank crew members, artillery crews etc. Standart pistols and SMGs chambered for pistol rounds were proved ineffective against enemy soldiers, wearing armour (bulletproof) vests, so FN Herstal developed a new round with enhanced penetration - the SS190. This round looks like scaled downt 5.56mm NATO round and forces the pointed, steel core bullet to the 600-700 meters per second at the muzzle, thus being capable to defeat standart CRISAT helmets and armour vests at reasonable distances (50-100 meters).

The P90 is a blowback operated, selective fire weapon. It is fed from 50-rounds box magazines, made from transluscent polymer. The magazine is being located above the barrel, with the cartridges being aligned at 90 degrees to the barrel axis. Each magazine has built-in ramp that rotates cartridge to align it with the barrel prior to chambering it.

The P90 controls are completely ambidextrous, with charging handles located at the both sides of the weapon, and the safety/fire mode selector is located below the trigger. The P90 also features downward ejection of the spent cases. P90 is built in bull-pup configuration, with polymer stock, and features built-in reflex collimator sight with 1X magnification and reticle automaticaly ajustable to the light level, as well as a set of the backup open sights. P90 may be equipped with special silencer, that should be used with special, sub-sonic variant of the 5.7x28mm cartridge.

P90 may be referred as a forerunner of the PDW (Personal Defence Weapon) concept, that arose in last 4 or 5 years.

P90 is used by Saudi Arabia, Peruan Special Forces and some special units of Thailand army, and offered for export by FN.

John Tompson founded the Auto Ordnance corp. in 1916, and began his developments in submachine guns with purchase of John Blish patent (1915), that described a delayed blowback automatic firearm. This patent described delayed blowback breech system in which a sloping metal wedge interlocked the breech block with the gun body. Under high pressure, as when the cartridge fired, the angle of the slope was such that the mating faces jammed solid. As the pressure dropped, the faces were able to slip across each other, the wedge moved up due to the slope, and the breech unlocked. This idea was used in all Thompson submachineguns except for M1 and M1A1 (those were simply blowback operated).

The first Thompson SMG appeared in 1919. The first serial manufactured model appeared in 1921 and was manufactured by Colt, as well as latest M1927 and M1928 models. 1928A1 & M1 series were manufactured by Auto-Ordnance and Savage, and licensed copies were manufactured by B.S.A. in Great Britain.
Currently, Auto-Ordnance (a part of the Kahr company) manufactures semi-auto only Tommy guns with lenghtened to 16" (405 mm) barrels for civilian market.

In general, all Tommy guns may be described as a select-fire, delayed blowback or simply blowback (M1) operated firearms. All tommy guns featured all-steel, high quality construction. Barrels are partially ribbed for better cooling.

Thommy guns became famous through "roaring twenties" in the USA, when, during the Prohibition times, many Tommy guns were used by both Police and criminals to spread the death across the enemies. The Hollywood made the Tommy gun the sign of the 1920's in the USA. But this gun was also widely used during the WW2 and later in Korean war, and proved itself as a reliable and powerful firearm. The main drawbacks of the Tommy guns were short effective range, heavy weight and high cost of manufacture.

Short listing of Thommy Gun models (according to Auto-Ordnance web site)
M1921 - first production model. Featured delayed blowback operations, machined steel receivers, charging handle located at the top of the receiver, detachable wooden buttstock and vertical forearm.
M1923 - unsuccessful attempt to increase effective range by introducing a new, more powerful cartridge, .45 Remington-Thompson.
M1927 - semi-auto only version of M1921. Barrel with Gutts compensator.
M1928 - also known as "Navy model". Select-fire version with horisontal wooden foregrip (also was manufactured with vertical foregrip) and sling swivels. Barrel with Gutts compensator.
M1 - First issued in 1943 as a simplified for war-time production variant of M1928. Select-fire, simply bowback operated, issued with 20 round "stick" magazines. Charging handle is located at the right side of the receiver. Plain barrel (without ribbing).
M1A1 - even more simplified M1 (with fixed peep-hole rear sights).

Greetings,

3 days ago, I got word the PX (Military shopping Center) had received 6 PS3 for the holidays. They were giving the first away (FREE) and the other 5 were raffled off to lucky people to purchase. I put my name in the

Well yesterday I received a call..."SIR you have won the PS3". I responded by "I will by to pay for it after lunch". The lady said "no SIR you WON the PS3"...again I replied with "yes mam I will pay for it after lunch." Finally the frustration in her voice was like,” Listen NUMBNUTS you don't have to pay for anything YOURS IS FREE!!" A little slow at times but I caught that!!

Today I am the proud owner of a PS3 with all the fixin's. Three games (Resistance, NBA 07, and Genji), Extra Controller, HDMI Cable, 60GB system and a PS3 Watch. How cool is that??

My friends were like,” You deserve that, you bust your butt taking care of people....It’s about time you got a reward."

Happy holidays to all and Best wishes for a bright and prosperous NEW YEAR.

Respectfully,

Doc
