by Electromechanical and Digital Weapons Systems
Modern military aircraft rely on sophisticated electromechanical and digital weapons carriage and release systems to carry a variety of bombs, missiles, rockets and other ordnance. These systems have become increasingly advanced with the development of digital avionics and networking capabilities. Leading military powers are continuing to invest in upgrading weapons systems to maintain air dominance.
The basic function of a weapons carriage and release system is to safely and securely carry different types of weapons externally or internally on hardpoints underneath the wings or within weapons bays of aircraft. Prior to engaging targets, the system prepares weapons for firing through arming, targeting and other procedures. At the appropriate time, the system releases weapons through mechanical or electrical firing signals to hit their targets.
Early electromechanical systems used solenoid valves, limit switches, pneumatic actuators and wiring harnesses to control the arming, targeting and release of individual weapons. Modern digital systems incorporate programmable logic controllers and interfaces that network multiple weapons and sensors through a centralized aircraft computer system. This allows for more flexible mission planning and integrated multi-target attacks compared to older analog point-to-point wiring.
Integrated Digital Avionics and Smart Weapons
Most contemporary combat aircraft feature integrated digital avionics suites that network all flight, navigation, targeting Weapons Carriage And Release Systems through a high-speed databus. For example, the U.S. F/A-18 Hornet introduces digital integration and networking through its AN/APG-73 radar and AN/AYK-22 weapons management computers. This enables data linking of targets and coordinated weapon employment between sections of aircraft.
Beyond digital networking between aircraft, modern “smart” weapons can now receive target updates, guidance commands and terminal attack parameters in flight through data links. Satellite-enabled weapons like the Joint Direct Attack Munition (JDAM) allow “fire and forget” attacks on pre-programmed GPS coordinates. Anti-radiation missiles can home in on enemy emitters identified by other networked aircraft.
The advent of integrated digital avionics, multimode sensors and network-enabled weapons has revolutionized modern air warfare. Smaller numbers of combat jets can now execute complex missions that in the past required larger force packages. Highly coordinated sensor-shooter operations and distributed concurrent engagements across wider battlespaces have improved strike effectiveness. However, digital integration also multiplies vulnerability to cyber and electronic attacks that disrupt mission-critical networking. Most militaries continue advancing both offensive and defensive cyber capabilities relevant to air missions.
Modular Weapons Bay and Hardpoint Configurations
To accommodate different precision-guided and “smart” munitions, modern weapons systems feature modular carriage options across multiple internal and external stations. Modernizing aircraft commonly upgrade legacy analog systems to utilize more weapon stations through enlarged internal bays and additional external hardpoints.
The U.S. F-15 Eagle exemplifies configurable weapons options through its nine external hardpoints. Four can be fitted with AIM-9 short range air-to-air missiles, while the other five usually carry long-range radar-guided missiles. Internally, conformal bays add space for more beyond visual range missiles, bombs and other payloads. For long-range intercept missions, two additional conformal fuel tanks can further increase its radius.
Like the F-15, other fighters such as the F/A-18 Hornet and Eurofighter Typhoon implement modular hardpoint configurations across their respective airframes. Modern strike aircraft go further with dedicated internal bays that can rapidly exchange pre-packaged arrays of different Joint Direct Attack Munitions, Small Diameter Bombs and other precision weapons. This “loadout flexibility” allows one airframe to tackle a diverse range of missions from air defense to close air support.
Integrated Aircraft Survivability Systems
Weapons carriage, along with other systems, must consider the survivability dimensions of modern air combat. Electrically-settleable hardpoints with self-sealing connectors protect against electric faults or takeoff/landing snags. Modern combat aircraft also employ integrated defensive systems which networking weapons stores.
Many fighters integrate decoy/countermeasure dispensing across their external stations. The F-15, for example, uses two wingtip mounted ALE-47 self-protection systems with automated chaff/flare deployment. Through digital interfaces, decoys synchronization complements active jamming during high-speed missile evasion maneuvers.
Signature reduction treatments lowers observable signatures from weapons bays or other stores. Internal carriage placement and protruding doors/access panels minimize detectable frontal profiles during supersonic dash attacks. Digital weapons bay management ensures powered internal rotations/elevations avoid potentially damaging mechanical feedback effects during violent aircraft maneuvers.
Continued research and development are expanding the capabilities of aerospace weapons carriage and release technologies. Hybrid-electric and all-electric implementations promise lower weight, simplified maintenance, and greater system commonality. Digital interfaces tightly integrate diverse payloads like hypersonic missiles, attritable drones and directed energy weapons. Post-launch capabilities like cooperative targeting handovers and coordinated salvos give modern combat aircraft exponentially greater lethality. Combined with resilient communication networks and onboard autonomy, tomorrow’s smart weapons systems will help sustain air supremacy for emerging defense challenges.
