Development The 155 mm DPICM M864 may be regarded as a logical development of the 155 mm DPICM M483A1 (see separate entry), as it features a base burn (base bleed) unit that enhances range without introducing the inherent inaccuracy limitations of rocket assistance motors. The projectile is stored, transported and handled in exactly the same manner as the 155 mm DPICM M483A1 and it is claimed that no special instructions or training are required in its use. Production commenced during FY87. Approximately 30,000 of these projectiles were sent to the Persian Gulf for Operations Desert Shield and Storm but they were not used operationally due to the omission of the appropriate software in the US Army's Battery Computer System (BCS). It should be noted that the DPICM M864 continues to utilise the same grenades as the earlier M483A1 so the lack of a self-destruct mechanism for dud dual-purpose grenades imposes training and other operational limitations. The 155 mm DPICM M864 is a joint development and marketing operation between the Chamberlain Manufacturing Corporation and Talley Defense Systems. Chamberlain produces the metal components used for the 155 mm DPICM M864, together with the associated grenades, at the Scranton Army Ammunition Plant, Pennsylvania. Production is also carried out by General Dynamics, Ordnance and Tactical Systems (GD-OTS). Talley Defense Systems is responsible for the Base Bleed/Base Burn (BB) unit produced since 1991, under US Army agreement at the Army Ammunition Plant at Joliet, Illinois, following low-rate initial production in Mesa, Arizona. The Joliet facility is capable of producing 15,000 units a month, although all production in the USA is currently in abeyance. Talley Defense Systems have delivered nearly one million BB assemblies. Description The 155 mm DPICM M864 is a separate loading munition with a streamlined forged steel ogive, a low-drag steel body (1340 or 4190 alloy) profile and a steel base closure (4340). The body rear is encircled by a gilding metal drive band. The nose is occupied during storage, transit and handling by a threaded energy absorbing lifting plug screwed into the fuze well. Before firing the plug is replaced by an M577 MTSQ fuze. The base of the fuze intrusion is surrounded inside the ogive by a booster charge, below which is a pressure plate. The projectile base is occupied by a two-piece Base Bleed Base Burn (BB) unit filled with a barrel-shaped Hydroxyl Terminated PolyButadiene (HTPB) composite propellant grain, developed by Talley Defense Systems, to be ignited by propellant gases on firing. The inhibited HTPB burns slowly for approximately 22 seconds in such a manner that the resultant gases fill the vacuum created by the aerodynamic air flow behind the shell. This reduces drag behind the projectile, therefore enhancing range. In operation, the M577A1 time fuze functions at the selected instant during the projectile's trajectory and initiates the booster charge located at the base of the fuze well. This initiates the expulsion charge formed by 90.7 g of M10 propellant. The resultant increase in internal pressure against the pressure plate and the contents forces the base closure outwards to push off the base burn unit. The shell contents are then ejected. Centrifugal forces disperse the entire grenade load radially from the projectile line of flight. The dual-purpose grenades are of two types, the M42 and M46 . The 155 mm DPICM M864 carries 72 of them; 48 M42 and 24 M46 . Both types of grenade are identical, although the wall of the M46 is heavier and thicker than that of the M42 . Serrations are embossed into the inner wall of the M42 grenades to enhance fragmentation; M46 grenades are not embossed. The grenades are unarmed while inside the projectile and are armed mechanically by spin after ejection. While in flight they are stabilised and orientated for impact by the deployment of a nylon ribbon streamer which also creates the spin to arm the grenade. The grenades detonate on impact under the control of an integral M337A1 graze fuze which mechanically initiates an M55 detonator. Each grenade contains 30.5 g of Composition A5 formed into a shaped charge with a 60º angle which is directed downwards to produce an anti-armour jet capable of penetrating approximately 70 mm of homogeneous armour plate. Fragmentation of the grenades' steel bodies produces anti-personnel effects. Both types of grenade are 82.55 mm long. The M42 weighs 208 g and the M46 213 g. The M42 and M46 grenades do not feature self-destruct mechanisms. The 155 mm DPICM M864 can also be fired in a fire registration mode. In this mode the expulsion charge is replaced by a shaped charge. When the fuze functions the resultant high-order detonation causes all 88 grenades to detonate, causing the projectile to fragment in the same manner as a conventional HE projectile and provide an airburst marker for fire registration. The 155 mm DPICM M864 can be used with the full range of propellant charges, including the M203 , apart from the basic M3A1 (green bag) and M119 charges. The M3A1 charge cannot take full advantage of the full potential range of the 155 mm DPICM M864 while the M119 is unable to ignite the base burn unit with sufficient reliability. The Propelling Charge M4A2 is a white bag charge using 5.897 kg of M1 propellant divided into a base charge and four increments for firing as Charges 3 to 7. The increments are tied together by four cloth straps. A 96.4 g clean-burning igniter charge in a red cloth bag is sewn to the rear of the base section and an M2 flash reducer pad is assembled in front of the base charge. The complete charge is 533 mm long. The Propelling Charge M4A1 is similar to the M4A2 but does not contain the M2 flash reducer pad (although this can be added if required), the base igniter contains black powder. The Propelling Charge M119A1 is a white bag charge with an igniter pad at the base and a ring-shaped flash reducer pad located on the front of the bag; the forward end also contains lead foil as a decoppering agent. The M119A1 contains approximately 8.62 kg of cool-burning M6 propellant with a central igniter consisting of a moulded nitrocellulose tube containing benite strands. The Propelling Charge M119A2 uses a red charge bag and does not have a laced jacket. It is provided with an igniter protector cap and tie strap which must be removed before firing; the circular red cloth igniter pad weighs 113 g. The M119A2 zone 7 is equivalent to the M119/M119A1 zone 8 charge. There are four 113 g potassium sulphate flash reducer increments located in side pockets. The M119A2 is 660 mm long. The similar charge to the M119A2 is produced by Eurometaal NV as the No 13. The Propelling Charges M203 and M203A1 (Charge 8S) were developed primarily for use in the 155 mm M284 cannon used with the M109A5 and M109A6 Paladin self-propelled howitzers, although they can be used with other similar long-barrelled pieces such as the CN79 Cannon used on the South Korean 155 mm KH179 Towed Howitzer. The M203/M203A1 is a single red bag charge encased in a tight fitting lacing jacket for strength. The bag has an igniter sewn to the base, a central core igniter extending through the centre of the charge and a flash reducer in front of the charge. The M203A1 differs from the M203 by producing cooler burning to increase barrel life, together with a reduction in blast and muzzle flash. When firing the 155 mm DPICM M864 from the M109A5 and M109A6 Paladin self-propelled howitzers and the M198 towed howitzer, a version of the Charge, Propelling, 155 mm: M203A1 with a rigid combustible case may be used. This version of the M203A1 weighs 14.06 kg, is 768 mm long overall and contains 12.7 kg of cool-burning M31A1E1 stick propellant. The combustible case and end cap contains a talc wear-reducing additive while the contents include a further wear-reducing additive and 156 g of lead foil to act as a decoppering agent. The use of this charge results in reduced flash and muzzle blast. The M119 series and M203 propellant charges should be fired using the Primer M82 only. Using the full M4A2 charge (white bag, Charge 7), the 155 mm DPICM M864 fired from the 155 mm M1A2 Cannon used on the M114A2 Towed Howitzer has a maximum range of 17,200 m. Using the M119A2 charge, the 155 mm DPICM M864 fired from the 155 mm M185 Cannon used on the M109A1 to M109A4 series of self-propelled howitzers, has a maximum range of 22,100 m. Using the M203A1 charge, the 155 mm DPICM M864 fired from the 155 mm M284 Cannon used on the M109A5 and M109A6 Paladin self-propelled howitzers, has a maximum range of 29,400 m. A similar range is attained when the 155 mm DPICM M864 is fired from the 155 mm FH-70 Howitzer using the full L10 propelling charge. Giat Industries of France produces a combustible case intended for use with all NATO standard 155 mm weapons. The case consists of a skirt, base and cover containing Charges 6 to 9; lower charges are formed using bagged charges. Use of this case system produces a barrel life at maximum charge of 3000 EFC. The muzzle velocities produced using this combustible case system are as follows: Charge 6 - 586 m/s Charge 7 - 705 m/s Charge 8 - 810 m/s Charge 9 - 830 m/s. Charge 9 can fire a projectile fitted with a base bleed unit to a range of 30,400 m. Chartered Ammunition Industries of Singapore produce a unitary charge, using cloth bags, which covers Charges 6, 7, 8 and 9. Known as the C20, this charge uses M6 propellant, is 610 mm long, 160 mm in diameter and weighs 10 kg. It is anticipated that future 155 mm propellant charge systems will involve the employment of the M231/XM232 Modular Artillery Charge System (MACS). Other countries are in the process of adopting similar modular charges.

Optical Mortar Proximity Fuze, PX581
Armament Any 60, 81 or 120 mm mortar bomb with standard fuze wells. Development Jointly by Junghans Feinwerktechnik and Noptel Oy to provide a new countermeasure resistant proximity fuze. Description The PX581 proximity fuze is independent of calibre and can be mounted on any 60, 81 or 120 mm bomb without adjustment. Because it is optronic, there are no known countermeasures. The PX581 is specifically intended for bursting at low altitudes to provide optimal terminal effects. Operating power is obtained through a windwheel generator that also provides a secondary arming function. The PX581 has a point detonating backup function. Optics are hermetically sealed and protected from temperature fluctuations to prevent accumulation of condensation. The fuze recognises ground surface, but does not react to clouds, mist, snow or rain. The fuze uses laser based ranging technology and sends out light pulses at the rate of 500 per second while the receiver constantly measures the distance to the target. The `smart' fuze recognises the target and detonates the bomb at the pre-programmed height with an accuracy of ±1 m. The fuze is fully compliant with MIL-STD-1316D, MIL-STD-331B, STANAG 4157 and STANAG 2916. There are both mechanical and electronic safety measures. A double bolt system and the windwheel assure mechanical compliance while the MIL-STD-1316A sensor electronically secures the fuze until it reaches its trajectory apex. Operating temperature range is from -40º to +60ºC exposed and from -55º to +71ºC in packaging.Читати далі

30 mm RARDEN gun ammunition
Armament RARDEN 30 mm gun L21A1 and L21A2 fitted to FV107 Scorpion and Sabre, Warrior MCV, 4K 7FA MICV 30/1 (Austria, prototype). The Boeing 30 mm Bushmaster II Chain Gun can also accommodate RARDEN ammunition. Development The first 30 mm RARDEN gun appeared in 1966 and the first service examples, the L21A1, followed during the early 1970s. The design philosophy called for an anti-armour gun with the emphasis on accuracy, as opposed to high rates of fire, combined with the ability to be mounted in light turrets. The ammunition selected for the RARDEN was based on that developed in Switzerland for the 30 mm Hispano-Suiza 831 L (now the Oerlikon Contraves KCB) cannon family, but subsequent development has resulted in what may be regarded as a separate ammunition family. KCB ammunition can be fired from RARDEN guns although RARDEN ammunition cannot be fired from KCB series cannon. The UK Design Authority for 30 mm RARDEN ammunition is BAE Systems , RO Defence. Description All 30 mm RARDEN ammunition involves fixed rounds, the projectiles are crimped to the necked drawn brass cartridge cases by a crimping ring engaging in a cannelure, just above the boat tailed base on the projectile. In most cases the drive bands are sintered iron pressed into place. The rounds are issued and loaded in charger clips of three. The brass cartridge cases are 170.3 mm long and have an L16 (RO 673) percussion primer filled with 0.97 g of gunpowder G20 threaded into the base; the rim diameter is 42.9 mm. The cartridge case is filled with variable amounts of granular NRN 141/RDN propellant. Ammunition available for the 30 mm RARDEN gun includes the following types: HE-T L13A2 The original HE-T round was the L8A1 but this was been replaced by the L13A1; the latest version is the L13A2 incorporating the RO 673 low-cost primer which was originally developed specifically for use with training ammunition. The projectile involved is machined from steel bar and contains 25.6 g of Torpex 2. An L86A2 impact fuze is threaded into the projectile nose while the shell base is occupied by an L11 tracer element which burns for a distance of over 2,000 m (time 2.6 seconds) after leaving the gun muzzle. APSE-T L5A2 The hardened steel pointed projectile used with this round has no fuze and is fitted with an anodised aluminium ballistic cap. It relies, for its secondary effects, on a payload formed by a pyrotechnic mixture of explosive and CS5390 smoke composition which is ignited by friction once the projectile has penetrated light armour. An L10A1 tracer is fitted in the base and burns for a range of approximately 1,500 m. This round is now rarely encountered. APDS-T L14A2 and L14A3 This APDS-T round was jointly developed by Royal Ordnance (now RO Defence) and PATEC of the USA. Introduced in 1980, it uses a plastic sabot with a lateral cross-section at the nose. Once the projectile leaves the gun muzzle the sabot breaks into four lateral segments, leaving the tungsten penetrator to complete its trajectory, marked for ranges out to at least 2,000 m by a tracer element in the penetrator base. Further result assessment is provided by a pyrophoric cap on the penetrator nose which provides a flash on impact with a hard target. The penetrator can pierce a 40 mm RHA plate angled at 45º out to a range of 1,500 m. Accuracy is stated to be half the dispersion of the HE-T round. Figures of 0.5 mil vertical and horizontal at 1,000 m have been quoted. The APDS-T L14A3 has a new type of tungsten penetrator in a plastic sabot and was introduced in 1986, the same year that a lower barrel wear propellant was first produced. The penetrator can pierce a 40 mm RHA plate angled at 45º out to ranges in excess of 1,500 m. One further round developed for the armour-piercing role was the APHC L6A1 carrying a tungsten carbide core; it is no longer manufactured. APFSDS-T An APFSDS-T round for use with the 30 mm RARDEN gun was developed with Radway Green as the lead facility. In April 1996, it was announced that this round had been selected to be developed and manufactured as the new 30 mm Armour-Piercing Enhanced Performance (APEP) to meet British Army Staff Requirement (Land) 4053. Under the terms of an April 1996 contract, Royal Ordnance was to have supplied around 225,000 APEP rounds between the years 1998 and 2000. It was planned that a DSRR round would be developed to match the APFSDS round for training purposes. In November 1998, it was announced that the APEP contract with Royal Ordnance (now BAE Systems , RO Defence) had been cancelled as the APEP did not meet the user's specifications. The requirement for a 30 mm APEP for RARDEN guns remains outstanding. TP-T L18A2 This round replaces the earlier L12A1 and L7A4 and uses a hollow machined steel body with an aluminium fuze plug. It matches the HE-T round ballistically, having the same propelling charge, and has a tracer burning for 2.6 seconds after leaving the gun muzzle. This round incorporates the low-cost RO 673 primer. In 1996, the British Army had a requirement for 55,500 of these rounds. DSRR L15A1 Originally known as the 30 mm Reduced Range Training Round (RRTR) RO 275, the L15A1 Discarding Sabot Reduced Range (DSRR) was developed to provide a low-cost training round for use on ranges with limited areas. It was originally designed to ballistically match the 30 mm L14A2 APDS-T round during the early part of its trajectory. The L15A1 DSRR is produced by RO Defence for the British Army order and is in service. The original order called for 660,000 units The 30 mm L15A1 DSRR is a fixed round with a tubular projectile carried inside a sabot similar to that used on the 30 mm L14A2 APDS-T. After firing, the sabot falls away leaving the tubular projectile to closely follow the trajectory of the L14A2 APDS-T projectile out to a range of approximately 1,500 m. At that range the projectile velocity will have fallen from an initial 1,300 m/s to around 700 m/s, and an aerodynamic effect comes into play to effectively choke the flow of air through the interior of the tube. The projectile then becomes unstable and falls to the ground after travelling approximately 2,000 m. The resultant range safety trace is thus considerably reduced. For example, the safety trace for an L14A2 APDS-T projectile is 11,900 m long and nearly 4,000 m wide. For the L15A1 DSRR the safety trace is 4,500 m long and 2,260 m wide. The L15A1 DSRR incorporates an annular tracer remaining effective out to 1,500 m. Although the 30 mm L15A1 DSRR is matched to the 30 mm L14A2 APDS-T, the same projectile design can be configured to match the 30 mm HE-T and APFSDS (still under development) projectiles. The changes required for such matching involve a change in the launch velocity, minor profile changes to the tubular projectile to alter the coefficient of drag and, in the case of the APFSDS, a change in the pusher material, which will be an aluminium alloy. The technology employed with the 30 mm L15A1 DSRR is also being considered for the 40 mm RRTR-T CTA round (qv).

Development The Cartridge, 105 mm: Blank, M395 is used for saluting purposes and to simulate battlefield noise. Many users produce their own Blank cartridges by converting suitably modified spent brass M14 cases. Prior to the beginning of FY98 about 284,000 M395 cartridges had been procured by the US armed forces. There will be no further scheduled procurement until some time during FY00 when $6,721 million has been allocated for the procurement of about 124,000 cartridges. Description The Cartridge, 105 mm: Blank, M395 consists of a shortened cartridge case known as the M15 . The M15 case is 70:30 brass, the M15B1 steel and the M15B2 aluminium. For early examples of the 105 mm Blank M395, black powder was contained in a cloth bag and held in position by a closing cup or plug assembly consisting of two pulp-board discs glued either side of a hard felt disc and cemented in position about 13 mm from the mouth of the case. Renovated or newly manufactured 105 mm Blank M395 cartridges are assembled with a loose 770 g black powder charge retained by a glass fibre closing wad and a polystyrene closing cup glued in place by an epoxy resin.

NORINCO 130 mm ERFB/HB HE and ERFB/BB HE
Armament 130 mm Field Gun M-46 ; 130 mm Field Gun Type 59 and Type 59-1; Factory 100 M59-1M; 130 mm Gun Model 1982 . 130 mm Self-propelled Gun (Catapult); NORINCO 130 mm Self-propelled Gun. Development The NORINCO 130 mm ERFB/HB HE and ERFB/BB HE projectiles were designed specifically for the 130 mm Type 59-1 gun, but may also be fired from the original 130 mm Field Gun M-46 or the NORINCO 130 mm Type 59 (the 130 mm Type 59-1 is a lighter and more manageable version of the 130 mm Field Gun M-46/Type 59). In appearance the 130 mm ERFB/HB HE and ERFB/BB HE projectiles resemble scaled-down versions of their 155 mm equivalents (qv). There are two further versions of these projectiles, the 130 mm ERFB HE (Nubb) and ERFB-B. These differ in the ability to take full advantage of the variable 130 mm charge system whereas the ERFB/HB HE and ERFB/BB HE are normally only used with the Full Charge to take maximum advantage of their enhanced range performance. The ERFB-HB version has not appeared in recent NORINCO literature and may no longer be available. By 1999, only the full 130 mm ERFB/HB HE was being marketed, so it is assumed that all other types are no longer available. Description The NORINCO 130 mm ERFB HE projectiles are separate loading munitions with their propelling charges contained in brass cartridge cases. The bodies of all these 130 mm ERFB HE projectiles are high-grade steel and are streamlined to the extent that almost the entire length is taken up by the ogive down to the twin copper drive bands. There are four riding nubs provided. The ERFB/HB HE uses a boat tail hollow base while the ERFB/BB HE is fitted with a Base Bleed (BB) unit to provide increased range; maximum range is 37,000 to 38,000 m. The explosive filling for these projectiles is usually 3.3 kg of TNT. Weight of the ERFB/HB HE projectile is 32.7 kg while the ERFB/BB HE weighs 32 kg. The ERFB HE (Nubb) weighs 32.41 kg. The weight for the ERFB-B has not been released. The nose-located fuze employed on the 130 mm ERFB/HB HE is the ML-5, ML-7A or ML-7B while that on the ERFB/BB HE is the ML-5 which can be set to super-quick, short or long delay. The ERFB/BB HE may also be fitted with an electronic fuze of unspecified type. These ERFB projectiles do not employ a special charge system but instead are used with the usual 130 mm variable charge system. The 70:30 drawn brass cartridge case involved is issued in two versions, a Full Charge version and a Reduced Charge propellant load. The Full Charge contains 13.5 kg of propellant loaded in a lower and upper bag, together with 2.5 kg of loose propellant in bundled stick form. An increment completes the Full Charge while removal of this increment creates Charge 1. The Reduced Charge weighs 6.75 kg and is supplied in a separate cartridge case. The top charge in the Reduced category is formed using the full complement of a base charge and two equal sized bags, forming Charge 2. Removal of one of the equal bags creates Charge 3 while removal of both equal bags, leaving only the base charge, creates Charge 4.
