Improved RPG Designs are Challenge Bar Armor Manufacturers
Since their introduction in operational service in 1961 the Rocket Propelled Grenade Mk 7 (RPG-7) over nine million RPGs have been produced, and hundreds of thousands fired in combat in war zones around the world.
Although RPG-7s proved their battle effectiveness in every conflict since the 1970s, NATO and coalition forces were surprised and ill prepared when they first encountered RPGs in Iraq in 2004. At the time these weapons were used primarily against heavy armored fighting vehicles, while Improvised Explosive Devices (IED) were directed at the less protected or unprotected tactical vehicles.
Realizing the gravity of this evolving threat, coalition forces began to protect their armored vehicles with add-on armor solutions designed to defeat RPGs. Since the PG-7VL High Explosive Anti-Tank (HEAT) warhead penetrates over 500 mm of steel armor with its shaped charge hitting the target, the only affordable solution was to eliminate the threat from hitting its target. Reactive add-on armor was an effective countermeasure applied to the heavier armored vehicles. Less protected vehicles were encapsulated with bar-armor cages.
The bar-armor cage is preventing RPGs from detonating their shaped charge close to the vehicle’s armor, thus penetrating the armor and causing severe internal damage. The cages are assembled from steel or aluminum bars. Bars are spaced in a form that would ‘trap’ the incoming warhead.
The operating mechanism of bar armor is simple and effective. As the RPG flies through the cage the warhead is smashed between two bars, deforming the conductive layers that form the ogive (cone) holding the piezoelectric precursor and covering the explosive charge. As the external liner bends in, it would touch the inner liner, causing a short circuit that disrupts the explosive triggering chain.
This image depicts the classical bar armor RPG-7 defeat mechanism.
The first-generation bar armor made of steel or aluminum were relatively heavy, weighing about 20-30 kg/square meter. Follow-on solutions that included counter-RPG net came in much lighter weight but suffered from the same lower efficiency with the same neutralization mechanism. Although the method provided reasonable protection, it did not provide conclusive results. In fact, it is likely that every second RPGs would ‘slip away’ and defeat the bar armor protection, either with full hollow charge penetration of the shaped charge, or while having a secondary explosion and piercing the platform hull (without forming the plasma jet). Such risk is especially evident on the less protected parts of the armored vehicles. Ceilings are often composed of thin armor and are rarely protected by bar armor cages or nets; the windshield and side windows are also vulnerable to secondary explosions.
Hence, this RPG protection is referred to as ‘statistical protection’, since the efficiency of the armor is not conclusive, but dependent on where and how each RPG will hit. Typical effectiveness of bar armor in defeating various RPG-7 warheads depends on the type of warhead (different manufacturers produce HEAT warhead diameters from 70 to 90mm). Hence, statistical protection ranges from 50 up to 70 percent for first and second generation.
In recent years, new types of bar armor, net protection systems and various hybrid systems were introduced and applied to most of the vehicles deployed in Afghanistan. More recently, French vehicles operating in Mali and elsewhere in Africa are also equipped with counter-RPG protection, with high level of performance, attributed to the latest, most advanced non-bar type solutions.
The reactive armor, first introduced by the Israeli army in the first Lebanon war in 1982 proved highly effective against RPGs and anti-tank missiles, driving the development of tandem warheads. The RPG-7 received such a warhead, designated PG-7VR in 1988. These warheads were first employed against US armor in Iraq in 2004.
Insurgents, becoming aware of the bar armor and its weaknesses, have employed several methods to defeat bar armor, among them rudimentary extensions of the impact sensor (piezoelectric trigger located at the tip of the round). These extensions would cause the fuse to activate before the ogive is smashed by the armor, thus activating the shaped charge ahead of the armor.
While passive RPG armor technology is improving, particularly by reducing weight and improving the theoretical statistical protection, more progress on the side of the RPGs would render the systems relying on the ‘smashing‘ totally ineffective.
In recent years, RPG manufacturers have also introduced enhancements to overcome common bar armor techniques and nets technology. “RPG manufacturers are applying protective layers at the base of the cone, thus avoiding potential short-circuits caused by deformation,” an armor expert told Defense-Update. Challenged by these improved RPGs, armor designers are now seeking to find alternative solutions by employing mechanisms that would guarantee the defeat of the warhead regardless of the type of RPG they are encountering.
According to our sources, since 2012 some RPG manufacturers have added a durable plastic sheet between the two conductive layers forming the ogive. This sheet prevents the two layers from short circuiting in case they are smashed, thus rendering the ogive operational even after it has hit a bar or passed through a net. The damaged RPG will continue flying and will hit the vehicle, initiating the shaped charge on contact. “In fact, as it will hit at an angle, the behind armor effect could be increased, as the spall is distributed at a larger lethal cone, hitting more of the vehicle occupants,” the expert warned. “We are going to see more and more of these in the battlefield.”
The PG-7VR projectile is a Russian-made tandem charge HEAT round developed by the state-owned enterprise Bazalt in 1988, and designed to defeat Explosive Reactive Armour (ERA). A 64mm shaped charge is carried forward of the main shaped charge, separated by an extension boom. This charge is intended to detonate the ERA of the target vehicle, allowing the primary 105mm charge to penetrate the regular armour. It weighs in at approximately 4.5kg, has an operational range of around 200m, and is supposedly capable of penetrating up to 600mm of Rolled Homogenous Armour (RHA) after detonation of ERA by the forward charge. The primary explosive is 1.43kg of OKFOL (окфол), an HMX-based compound.
OG-7V - Fragmentation, 2 kg, diameter 40mm, lethal radius 7 m (23 ft) (vs. body armor) 150m w/o Body Armor. OG-7 (or a Bulgarian copy) anti-personnel projectile. These projectiles are designed to engage enemy personnel, disabling them through a combination of HE and fragmentation effects. The warhead has a point-detonating fuze, is 40mm in diameter (the same diameter as the expelling charge/rocket motor), and has an effective range of 180m, and a nominal maximum range of 900m`. The 2.0kg projectile contains approximately 210g of A-IX-1.
The TBG-7V is a thermobaric projectile developed sometime in the late 1980s. It is designed to disable enemy personnel in urban or mountainous terrain (including entrenched enemy combatants in bunkers, buildings, and the like) through a combination of heat and overpressure, but also has a secondary fragmentation effect. The blunt-nosed warhead is 105mm in diameter, and weighs approximately 4.5kg. It contains 1.9kg of 100MI-3L (100МИ-3Л) thermobaric composition, as well as 0.25kg of A-IX-1, an RDX-based compound. The effective range of the projectile is given as 200m, with a maximum range of 700m. The lethal radius of the projectile is 10m.
The Chinese-manufactured Type 69 HE Airburst (DZGI-40) projectile features a warhead that operates in a similar fashion to ‘bounding’ anti-personnel (APERS) landmines. When the 75mm warhead strikes the ground, it is propelled upwards by a jump mechanism, and detonates at a height of approximately 2 metres. Somewhere in the region of 800 steel balls and fragments of the case are propelled outwards, giving the warhead a lethal radius of 15m. The projectile is 825mm in length, weighs 2.8kg, and has an effective range of up 1,500m. These projectiles are, unsurprisingly, designed to be employed in an anti-personnel role. They are typically outfitted with a Chinese ‘DREOI’ fuze.

Airtronic USA RPG-7
Airtronic USA Mk.777 lightweight grenade launcher - korištenjem novih materijala masa oružja je snižena do 3,5kg uz zadržavanje svih borbenih karakteristika.
Popularity and wide availability of RPG-7 rounds caused the US-based defense contractor company Airtronic to create its own version of this venerable weapon, which can use all types of RPG-7 compatible rounds. Original Airtronic RPG-7 grenade launcher features solid construction with ordnance steel barrel and some useful extras, such as Picatinny rails that can host variety of sights (iron, red dot, telescopic, IR / Night) and adjustable shoulder stock. The more recent Airtronic Mk.777 antitank grenade launcher is especially interesting as it combines all combat capabilities of the basic RPG-7 weapon with extremely light weight, which is achieved by using steel-lined polymer barrel.
The Airtronic RPG-7 is a shoulder fired, single-shot, smoothbore recoilless launcher. Grenades are loaded from the front, and the rear of the barrel is fitted with venturi nozzle. Because of the recoilless design, there is a dangerous backblast zone, more than 20 meters/60ft long. The antitank grenades are of combination type, using a charge of smokeless powder for RCL-type launch. Once grenade reaches safe distance from the shooter (about 10-20 meters), the built-in rocket booster engine ignites and further accelerates the grenade, greatly enhancing the effective range (up to 500+ meters for single warhead grenades, up to200+ meters for much heavier tandem or FAE grenades). Airtronic USA RPG-7 launcher is fitted with backup iron sights and has several Picatinny rails for easy installation of various optical or IR / Night sights. RPG-7 uses mechanical ignition system with manually cocked external hammer, and a single-action trigger. Because of this, grenade must be properly aligned with the firing mechanism upon loading.

Modernizovani oklopni transporter BTR 50PK
Modernizovani BTR 50 na Partneru 2011
U saradnji Jugoimporta, Vojno Tehnickog instituta i namjenske industrije Srbije, za stranog narucioca uspješno je realizovan projekat modernizacije sovjetskog oklopnog transportera BTR-50PK.
Na gabaritnom vozilu iz pedesetih uglavnom su vršena poboljšanja pogonskog dijela i oružnog sistema. Standardni motor zamijenjen je motorno - transmisionom grupom sa BVP M 80A snage 235Kw. Zahvaljujući boljoj transmisiji i jačem motoru povećana je prohodnost za 20%. Maksimalna brzina povećana je na oko 55km/h. Na vozilu su zadržana dva propelera za kretanje po vodi.
Za povećanje vatrene moći iskorištena je kupola M91 namijenjena modernizaciji BVP M80A. Radi se o jednočlanoj kupoli sa sa topom M-86 od 30mm (30x210mm), spregnutim mitraljezom 7,62mm i dvostrukim lanserom PORV raketa. Umjesto mitraljeza kao opcija nudi se ugradnja teškog mitraljeza 12,7mm i automatskog bacača granata 30mm.
Kod PO raketa ponuđene su modernizovane varijante "Maljutki" sa poboljšanom kumulativnom, tandem bojevom i aerosolnom bojnom glavom. Borbeni komplet čine 4 rakete, 2 na vozilu i 2 unutar vozila.
Na kupoli su montirana i 4 bacaca dimnih kutija M-79, kalibra 82mm. Nisanski sistem je preuzet sa BVP M-80A i činili su ga dnevni DNS-1 i nocni nisan PNS-1, ali je na zahtev narucioca ugradjena integrisana nisanska sprava DNNS-30, sa dnevnim i noćnim nišanskim kanalom koji ima pojačivač svijetlosti druge generacije. Nisanska sprava uveličava 5,3X pri gadjanju kopnenih ciljeva, odnosno 1,1x pri dejstvu na vazdušne ciljeve. Vidljivost u noćnim uslovima je do 1100m, sa mogućnošću uveličanja od 7,2X.
Oklopna zastita kupole sastoji se od zavarenih čeličnih ploca debljine 25mm na celu, 13mm na boku i 8mm na zadnjem dijelu kupole. Smatra se da je time obezbijeđena zaštita od kalibra 20mm sa daljina preko 300m i kalibra 7,9mm sa 100m.
Oklopno tijelo samog vozila štiti sa čeone strane od municije 12,7 ispaljene sa većih daljina i od municije do 7.62mm sa boka.
Desantni korpus čini 10 strijelaca i 3 člana posade - vozač, komandir i nišandžija. U odnosu na originalnu koncepciju vozila brojno stanje u desantnom korpusu je prepolovljeno, a posadi je dodat jedan član.
Na Yugomportovom projektu modernizacije BTR 50PK nisu vršeni konstrukcioni zahvati na tijelu vozila tako da je način desantiranja strijelaca i oklopna zaštita na tijelu vozila ostala ista kao na originalu. Borbena masa povećana je na 15,5 tona u odnosu na 14,3 tone kod originala.
Ukrajinska modernizacija BTR 50 iz harkovskog Morozova. Namjena modernizacije je povećanje vatrene moći i prohodnosti vozila. Modernizacioni paket oružnih sistema u ponudi ima dva borbena modula opremljena sa automatskim topom 30mm (ZTM1 ili 2A72), mitraljezom 7,62mm, automatskim bacačem granata i PORVom (Konkurs).
Za zamijenu originalnog motora nudi se četvorotaktni, šestocilindrični dizel motor UTD 20 snage 300ks. Takođe modernizacija obuhvata zamijenu originalne transmisije sa planetarnim menjačem sa volumetričkom hidrauličnom transmisijom.
Modernizacijom se dobija povećanje vatrene moći i borbenih sposobnosti, smanjenje potrošnje goriva i uvećanje vuče u odnosu na masu. Masa vozila povećana je na 16,6 - 16,8 tona, a brzina na 75km/h sa mogućnošću plivanja pri brzinama od 9 - 10km/h.
Ukrajinci paket modernizacije BTR 50 nude u dvije verzije sa osnovnom razlikom u osmatračko - nišanskom bloku na oružnom sistemu.
Verzija 1 obuhvata TKN-5 day/night sight with laser range finder PZU-7 day sight for firing at air and ground targets 9Sh119M1 anti-tank guided missile system sight,
Verzija 2 - OTP-20 optical television system with laser range finder and fire control system PZU-7 day sight for firing at air and ground targets 9Sh119M1 anti-tank guided missile system sight.
Verzija 2 stabilisana je u dvije ravni, Verzija 1 samo u vertikalnoj.
Po zahtjevu naručioca, Ukrajince nude i mogućnost oblaganja vozila kevlarskim tipom zaštite, navigacionim sistemom i klima uređajem.
Posadu čini (oko) 10 ljudi.

The bubble below the nose of this BT-67 gunship is the forward looking infrared camera. All BT-67s have over-wing exhausts to minimize their infrared signatures.
“We have customers telling us, ‘This is a good platform for survey work, for maritime patrol activities and even tactical maritime patrol,’” Weigt said. “We’re seeing expanded interest in those applications. I think that’s because we live in a very troubled world. The official U.S. product for those operations is the AC-130 Hercules, which is a high-dollar product. We’re the ‘low-price spread,’ but we can still get the job done.”
The airplane has proven itself to be such an excellent platform for surveillance and tactical interdiction activities, Basler is concentrating on new military applications, such as search radar and advanced communications and intelligence equipment.
“The BT-67 can loiter over an area for ten hours, monitoring and downloading information,” said Weigt. “It’s low cost, and it keeps human intervention in the mix. We’re a low-altitude application, at around 5,000 to 15,000 feet, where our infrareds are most effective. We do, however, have the capability to fly at 25,000 feet.”
The basic BT-67 aircraft costs $4.5 million, and an aircraft equipped with maximum capability would run $13-plus million. Such an aircraft is classified, but it would probably contain search radar, infrared, intelligence of some level, listening devices, secure communications, night vision compatibility, an on-board oxygen generation system and probably a gun capability.
One area where change has made a significant difference is in the gunship (nicknamed Fantasma). The gunship can climb to 15,000 feet, and isn’t pressurized.
“With the old oxygen bottle system, we had four bottles,” Weigt said. “If someone was shooting at you and hit one of the bottles, you became a flying bomb. To give the crew some protection, we had to add armor protection around the bottles. Then you had 600 pounds of weight added to the airplane, and the oxygen was still dangerous. The new OBOG is very low in pressure, around 40 psi, compared to the 1,800 psi in the bottles.”
“All of the panel lights had to be modified, so they wouldn’t interfere with night vision goggles,” he said. “Every switch has its own light source. With just one switch, everything goes from day to night or from normal to night. Everything is filtered. Even at night, you’ll see color on the weather radar.
This line drawing of the BT-67 shows the external changes made to the old DC-3. Metal control surfaces replaced the old fabric surfaces, greatly reducing maintenance.

“That, combined with a new battery system exclusive to Basler, is important for our customers,” said Weigt. “It’s a non-hazmat battery that’s virtually maintenance free. We tried the recombination technology batteries, and found them to be 80 percent stronger, lighter and more durable. They cost less, and don’t require special procedures for hazardous shipping.

Things like that keep the business refreshed and our customers coming along.
