Advanced hit efficiency and destruction (AHEAD) ammunition [1] is a type of airburst round ammunition that releases a cloud of sub-projectiles just ahead of a target, enabling it to engage conventional as well as low, slow and small (LSS) air threats including unmanned aerial vehicles and perform counter rocket, artillery, and mortar duties. The 35 mm variety produced by Oerlikon Contraves splits each projectile into 152 tungsten [2] submunitions "that form a cone-shaped pattern to destroy a target's control surfaces and other vital components". [3] This type of ammunition is listed as an official acronym at the British Ministry of Defence. [4]
There were, in 2017, four types of 35 mm AHEAD ammunition: [5] [ user-generated source ]
AHEAD ammunition was developed as early as 1993. [6]
In 2011, the government of the Republic of China in Taiwan procured itself a Skyguard system, which is based on the AHEAD ammunition. [7]
In 2012, AHEAD was delivered to the German Air Force by Rheinmetall for their MANTIS Air Defence System. [8]
At the 2018 Euronaval trade show, the Rheinmetall Oerlikon Millennium Gun was noted as able to fire AHEAD ammunition. [9]
In 2018, AHEAD ammunition-capable Oerlikon revolver guns were proposed to the Egyptian Ministry of Defense by the manufacturer, in order to update its air defense system. [10]
In January 2019, the South African Defence Force boasted about its upgraded ability to fire AHEAD ammunition at airborne targets via a networked multi-gun emplacement. [11]
In March 2021, Rheinmetall Air Defence unveiled the Skyranger 30, an air defense turret that uses a 30 mm gun firing a 30 mm version of the AHEAD projectile. [12]
In June 2021, Rheinmetall tested its 35 mm revolver gun against drone swarms with the use of AHEAD ammunition. Firing PMD 428 rounds, [13] [14] an eight-drone swarm was neutralized with an 18-round burst, most of them being destroyed with the first six rounds. [15]
In mid-2022, AHEAD was the subject of study by a group of Chinese scientists. [16]
In August 2022, the munitions were listed on the scrapped purchase order for the towed air defence gun missile systems (ADGMS) of the Indian Ministry of Defence. [17] It seemed the matter excited some controversy around this time. [18]
In October 2022, the munitions were listed as one of the technical requirements for a gun that would be procured by the Indian MoD. [19]

Oerlikon Contraves was a Swiss anti-aircraft artillery manufacturer famous for its adaptation of the 1916 20 mm Becker as the Oerlikon 20 mm autocannon design, which was used in the Second World War and still in use today. Copies and derivatives of these designs were made by German, French, British, and Japanese weapon manufacturers. Oerlikon Contraves was purchased by Rheinmetall in 1999.
The Boxer is a multirole armoured fighting vehicle designed by an international consortium to accomplish a number of operations through the use of installable mission modules. The governments participating in the Boxer programme have changed as the programme has developed. The Boxer vehicle is produced by the ARTEC GmbH industrial group, and the programme is being managed by OCCAR. ARTEC GmbH is based in Munich; its parent companies are Krauss-Maffei Wegmann GmbH and Rheinmetall Military Vehicles GmbH on the German side, and Rheinmetall Defence Nederland B.V. for the Netherlands. Overall, Rheinmetall has a 64% stake in the joint venture.
A revolver cannon is a type of autocannon, commonly used as an aircraft gun. It uses a cylinder with multiple chambers, similar to those of a revolver handgun, to speed up the loading-firing-ejection cycle. Some examples are also power-driven, to further speed the loading process. Unlike a rotary cannon, a revolver cannon only has a single barrel, so its spun weight is lower. Automatic revolver cannons have been produced by many different manufacturers.
The Flugabwehrkanonenpanzer Gepard is an all-weather-capable West German self-propelled anti-aircraft gun (SPAAG) based on the hull of the Leopard 1. It was developed in the 1960s, fielded in the 1970s, and has been upgraded several times with the latest electronics. It has been a cornerstone of the air defence of the German Army (Bundeswehr) and a number of other NATO countries.
The Oerlikon GDF or Oerlikon 35 mm twin cannon is a towed anti-aircraft gun made by Oerlikon Contraves. The system was originally designated 2 ZLA/353 ML but this was later changed to GDF-001. It was developed in the late 1950s and is used by around 30 countries.

Skyshield air-defence system is a modular, light weight, short range air defense (SHORAD) system developed by the Swiss corporation Oerlikon Contraves. The successor to the Skyguard defense system, Skyshield is intended to rapidly acquire and destroy threatening aircraft and missiles, as well as to fulfill a C-RAM role.
Counter rocket, artillery, and mortar, abbreviated C-RAM or counter-RAM, is a set of systems used to detect and/or destroy incoming rockets, artillery, and mortars before they hit their targets, or provide early warning.
An airburst round is a type of tactical anti-personnel and anti-aircraft explosive ammunition, typically a shell or grenade, that detonates in midair, causing air burst effect fragment damage to enemy personnel or aircraft. In the latter case, airburst rounds are used in anti-aircraft or "zenith" cannon, known in military slang as FLAK or ack-ack.
The ADS, formerly known as AMAP-ADS, is a hard-kill active protection system (APS), developed by the German company ADS Gesellschaft für aktive Schutzsysteme, a subsidiary of Rheinmetall and IBD Deisenroth Engineering, as part of their Advanced Modular Armor Protection concept.

Its most noticeable use was on the JA 37 Viggen fighter mounted in a conformal pod as the akan m/75. The KCA fires a 30 mm × 173 mm shell that is 50% heavier than the NATO standard ammunition used on ADEN and DEFA cannon. It can fire up to 1350 rounds per minute at a muzzle velocity of 1030 m/s, with an effective range of 2,500 m (8,200 ft)
The GOKDENIZ complex along with Aselsan ATOM 35mm airburst ammunition is an all-weather-capable Turkish 35 mm dual barrel close-in weapon system (CIWS) developed by Aselsan. It is a CIWS variant of KORKUT Self-propelled anti-aircraft gun.
The SkyKnight is an all-weather multi-target short-range air defence missile. It was developed by Halcon Systems and is the United Arab Emirates' first designed counter-rocket, artillery, and mortar (C-RAM) missile. SkyKnight is planned to be integrated into Rheinmetall Skynex air defence system. Skynex is a fully networked system of sensors and effectors linked via a tactical communications network to provide a mostly automated layered defence against various aerial threats. Up to four 6.1 m (20 ft)-long SkyKnight missile launcher units (MLU) with 60 rounds each can be controlled in a Skynex battery. An MLU can launch up to five missiles in one second and each can simultaneously fire 20 at one time to neutralize 80 incoming targets. The missiles are capable of intercepting manned and unmanned aircraft and helicopters at 10 km (6.2 mi), precision guided munitions (PGMs) and cruise missiles at 6 km (3.7 mi), and RAM projectiles at 4 km (2.5 mi). The Skynex system combines the SkyKnight with up to four Oerlikon Revolver Gun Mk3 35 mm revolver cannons to handle anything that penetrates through the missile defenses.
