The Manticore Multi-Role Gun and Missile System (export designation: Flugabwehrwaffensystem Manticore ("air defence weapon system Manticore") or Anti-aircraft missile and gun complex "Mantikora") is a day/night, all-weather capable, automatic controlled, quick reaction air defence system designed as a final line of defence against "leakers" i.e. incoming missile threats that have not been jammed, decoyed or shot down by longer ranged weapons. The core components of a Manticore system are:
- • Dory Close-In Gun System (CIGS) (export designation: Nahbereichs-Flugabwehrsystem Dory ("short range air defence system Dory") or Anti-aircraft gun complex "Dory"), based on a single 40 mm cased telescope ammunition (CTA) automatic cannon. It engages targets at close range and in the line-of-sight using laser guided projectiles with the accuracy to hit missile airframes;
• Xiphos Inner Layer Missile System (ILMS) (export designation: Nächstbereichschutzsystem Xiphos ("air defence protection system Xiphos") or anti-aircraft missile complex "Xiphos") comprising a pair of 12-pack launcher canisters on a trainable platform. It fires RIM-199A Xyston high velocity missiles that use multi-mode guidance with midcourse radar guidance and semi-active laser guided independently targetable "hittile" (hit-to-kill missile) submunitions to defeat low altitude and sea-skimming missile threats.
A Manticore air defence system is fully modular containing any combination of gun only, hybrid gun-missile or missile only weapon mounts scalable from a single weapon station to multiple stations that provide overlapping fields of fire and salvo fire capability. Weapons can be operated autonomously in stand-alone or parallel fashion using on-mount closed-loop spotting systems and fire control directors, or be fully integrated to an own-ship combat system or as part of a layered anti-air warfare system. Using salvo fire a hybrid gun-missile installation can counter time-on-target saturation missile attacks and swarming surface attackers, achieving single-shot kill probabilities (SSPK) exceeding 99%. Dory and Xiphos weapon stations are fully self-contained as bolt-on non-deck penetrating mounts to allow flexible placement aboard ships of any type or size. Designed from the onset for retrofit to older vessels the mounts can provide a 1:1 drop-in replacement for Phalanx, SeaRAM, RAM, Goalkeeper, Mantis and Millennium Gun mounts with full compatibility with standard naval electrical systems (e.g. 440V/60Hz busbar), and RS-422 serial bus and Ethernet fibre-optic networks.
The Dory Close-In Gun System (CIGS) is an unmanned automated gun mount armed with a medium calibre dual purpose (anti-air/anti-surface) rapid fire automatic cannon and equipped with optronics director, closed-loop automatic digital fire control system and ballistic computer for autonomous rapid fire control and weapon reaction. The cannon, complete with linkless feed mechanism and dual-feed magazines, is enclosed within a low radar cross section faceted gun house constructed from lightweight self-supporting fibreglass-phenolic laminate armour that provides small arms and fragment protection from air bursting munitions. The mount is twin-axis stabilised with all-electric servos and solid-state drives capable of high and low elevation angles to engage plunging threats in the zenith to sea skimming threats, and rapid slewing through azimuth angles to provide 360° coverage with high tracking speeds to engage crossing targets. The Dory gun system is capable of automatic target engagement with very short reaction times (<2 sec) from first detection to ready to fire, having autonomous search, detection, threat evaluation, prioritisation (from up to 20 targets), tracking, engagement and kill assessment functions provided by the weapon control system. The on-mount sensors include a gyro-stabilised large-aperture day/night all-weather passive TV/FLIR auto-tracker, laser rangefinder and laser emitter/auto-tracker. The gun is fully networkable for integration to anti-air warfare systems, allowing it to be cued and directed automatically by off-mount sensors, or manually aimed/remote-controlled by shipboard combat systems.
The Nexter Systems CTAS 40 is a single barrel 40 mm L/70 cased telescoped ammunition (CTA) externally powered air-cooled automatic gun with a firing rate of 180-200 rounds/min. The gun features an electrically actuated firing system and 70 calibre autofrettaged chromium plated rifled high strength steel barrel with fume extractor and integrated muzzle brake. To reduce radar cross-section and thermal signature a composite gun shroud with titanium end frames and carbon fibre shell is fitted to the barrel. The gun is mounted on frictionless bearings inside the Dory gun house and is twin-axis stabilised for tracking and laying on targets. Using precision all-electric azimuth and elevation drives it can track crossing targets and ensure tight dispersion of rounds for high accuracy. The ammuniton handling system is a low inertia linear-linkless belt drive mechanism feeding from a pair of 105 round high density packing endless ammunition conveyor magazines mounted either side of the trunnion. Rounds are transported in a serpentine loop from the magazine and loaded at the breech by a vertical sliding breech block, with spent casings transported back to the magazine for storage. An ammunition port on the gun house allows easy upload or offload of rounds and casings. The weapon has a total of 210 rounds of ready to fire ammunition sufficient to engage a minimum of ten anti-ship missiles or 20 surface targets without reloading. The dual-feed system provides flexibility to load both anti-surface and anti-air munitions selectable through the fire control system.
Nexter Systems provides a full suite of compact cylindrical 60×255 mm CTA ammunition that is only half the length of standard Bofors 40 mm ammunition and containing 2.5 times the payload volume of conventional 30 mm ammunition for enhanced on-target effects. These consist an Anti-Aerial Airburst (A3B) round for engaging air threats to a maximum range of 4,000 m, and a General Purpose Round Air Burst (GPR-AB) round for engaging surface threats out to 2,500 m. Both rounds have multi-option programmable time delay (i.e. chronometric) fuses that are set at launch by an induction circuit in the gun via the fire control system. In the case of the A3B shell the round is programmed to explode ahead of a target to project a 100 by 200 metre cone of 200 spin stabilized 51 grain tungsten alloy fragments in a radial pattern into the predicted flight path. Burst lengths between 1 to 10 rounds (for a maximum of 2,000 lethal fragments) ensures high hit probability and lethality against missile airframes, drones and hovering helicopters. The GRP-AB differs by featuring a more conventional dual-purpose high explosive fragmentation (HE-FRAG) warhead for engaging surface targets. The chronometric fuse in this case can be programmed in either air burst (AB) mode where it detonates over a target to produce a 125 m² casualty/lethality zone, or point detonating (PD) mode to penetrate light protective armour.
Sequoia Dynamics has also developed a laser beam riding self-steering kinetic hit-to-kill precision guided munition, the Cased Telescoped Guided Projectile (CTGP), that is handled like any other round of CTA ammunition and is fired using a discarding sabot. The 25 mm subcalibre free flight projectile has a tungsten alloy housing and contains small canard fins for steering, guidance and control circuitry and a laser seeker. Employing semi-active laser (SAL) beam riding guidance and proportional navigation rules it steers a constant collision course on to a target by following on- or off-mount laser trackers that maintain line-of-sight to the target during an engagement. The 30,000 g acceleration from a gun barrel imparts sufficient kinematic performance on the round for it to track evasive and manoeuvering targets such as pop-up sea skimming threats. CTGP ammunition has the following characteristics:
Precision accuracy to hit small air targets;
High hit probability against all targets;
Long range accuracy with fewer rounds per salvo (2 round burst)/increased number of stowed kills per weapon;
High effectiveness against hardened targets;
Cheaper per kill than guided missiles.
The Xiphos Inner Layer Missile System (ILMS) consists of twin 12-pack canister launchers mounted on a trainable non-deck penetrating mount loaded with RIM-199A Xyston quick reaction line-of-sight point defence missiles pre-loaded into launch tube/shipping containers, and guided by a combination of on-mount gyro-stabilised optronics director, scanning fibre lasers, lightweight surveillance radar and multi-channel tracking/guidance radar. The ILMS is fully self-contained mounted on its servo-driven turntable, using all-electric solid-state drives for fast reaction and rapid slewing to accurately track threats. As with the Dory gun system the ILMS can operate autonomously or integrated into an anti-air warfare (AAW) system. The engagement sequence is automated and begins with detection by on- or off-mount surviellance radar, identification friend-or-foe (IFF) interrogation, the incorrect response generating an air warning and automatic hand over to the on-mount auto-trackers (radar, TV/FLIR and laser) that slew the turntable to track the target or targets, with threat classification, prioritisation (with the ability to track 100 targets and engage 12 simultaenously), calculation of the optimum intercept point for the missile (typically at 1-2 km) by on-mount or a AAW system processor, and firing on the target(s). An engagement from first detection to successful intercept lasts only 7 seconds, with the system capable of engaging a single target with a two-salvo launch for 100% kill probability and multiple targets in salvo fire with only a 0.5 second launch delay.
RIM-199A Xyston flight configuration, showing booster,
missile bus and three hit-to-kill "hittile" submunitions
The RIM-199A Xyston is a lightweight, all-aspect, high velocity, short-range air defence missile designed to destroy attacking medium- to low-altitude high speed threats including anti-ship and cruise missiles. The missile has a two-stage propulsion system consisting of a jettisonable ejector motor or booster and a flight motor with four pop-out rectangular control fins that deploy after booster seperation. Guidance is provided by a passive millimetre wave (mm-wave) radar seeker housed in a forebody faring. The missile airframe contains electric actuators for the control surfaces and an electronic safe, arm and fire (ESAF) device that powers up the missile within milliseconds for quick reaction.
The complete missile including ejector motor is 1450 mm long, with a body diameter of 139.7 mm, fin span of 274.3 mm and launch weight of 50 kg. The warhead is a trio of hittiles (hit-to-kill missiles) attached by brackets on to a missile bus ahead of the second stage flight motor. Resembling a slender dart each hittile is 470 mm long, 27 mm in diameter, weighing 1.25 kg each, with cruciform stabilising delta tail fins and two small canard fins on a rotating forebody. Each hittile has a laser seeker and kinetic energy (KE) frangible warhead consisting of an alloy casing, high density tungsten nose cap and a small FOX-7 (1,1-diamino-2,2-dinitroethene) insenitive munition bursting charge activated by a delay-contact fuse to maximise after penetration effects.
Both motors use ammonium dinitramide/glycidyl azide polymer (ADN/GAP) low smoke producing composite propellant in a very high Isp (specific impulse) formulation of 70% bimodal prilled ADN and 30% GAP-based energetic plasticiser to produce their high thrust performance. The first stage booster motor completely burns out inside the launch tube to protect the launcher platform and on-mount sensors from backblast and minimise launch signature, ejecting the missile to a distance of 100 metres downrange before falling away to initiate the second stage flight motor to accelerate the missile bus to Mach 4. The motor provides continuous thrust for 4-5 seconds of powered flight depending on the intercept trajectory, boosting the missile bus to a maximum speed at burn out of Mach 4.5 and capable of 35 g skid-to-turn manoeuvres to track evasive targets, a maximum range of 8 km and an intercept altitude envelope of 0 to 6,000 m.
Guidance in the boost and mid-course flight phases is by radio command link with semi-active radar homing (SARH), otherwise known as track-via-missile (TVM) guidance. The mm-wave seeker detects and tracks radio frequency (RF) energy reflected from the target illuminated by on- or off-mount radar and downlinks the positional data to the fire control system for processing. The highly accurate fire control quality track data is used to compute the optimum release point for the hittiles, with trajectory shaping guidance commands uplinked to the missile navigation system to maintain a constant collision course towards the target. The goal is to place the missile into an "engagement basket" within the field-of-view of the hittiles laser seekers. This system is highly effective against manouevering targets at low altitudes and slant angles and in high clutter conditions, employing multi-channel track-while-scan and illumination radar and digital signal processing to manage multiple simultaneous intercepts with unjammable high speed two-way datalinks.
In the terminal phase or end game the hittiles separate from the bus after motor burn out, by sheering of powder metal connectors, and continue towards the target in free-flight by inertia alone. Travelling at an impact velocity of 1,250 m/s (Mach 3.67) each hittile has the kinetic energy and explosive power equivalent to a APFSDS shell fired from a Bofors 40 mm gun. Terminal guidance is by semi-active laser (SAL) illuminated by a pair of on-mount scanning lasers tracking the target and producing a 2D matrix of fast pulsed laser spots in an expanding diamond pattern around the missile airframe or air target. Flying in a tight pattern 1.5 metres in radius the hittiles are independently guided on to the target to increase the hit probability from a single shot. Setback (i.e. acceleration forces) arm the warhead, which detonates after peneration of the target to produce maximum target destruction.
The Xiphos weapon mount is equipped with separate pulse Doppler target acquisition and surveillance radar and continuous-wave (combined tracking and illumination) engagement radar that employ frequency agile coherent wide-band mm-wave illumination to detect and track low radar cross-section (RCS) and high velocity targets (e.g. missile airframes). Each system contains high-speed digital signal processors, IFF interrogator and decoder electronics, a solid-state traveling-wave-tube (TWT) amplifier, and phased-array planar antenna made from galium-nitride (GaN)-based monolithic microwave integrated circuit (MMIC) transmit/receiver (T/R) modules. Capabilities include fully automatic target detection and tracking; multi-target track-while-scan (TWS) digital processing; extremely low sidelobes and peak power (<5 watts) for low probability of counter-detection; low noise coherent Doppler processing for high range resolution, low signature target detection and tracking of manouevering targets; and wideband frequency agility, pulse compression and constant false alarm rate (CFAR) processing for jamming resistance, decoy discrimination and rain, sea and atmospheric clutter suppression.
The surveillance radar is a three-dimensional (i.e. range, bearing and elevation) pulse Doppler radar operating at K-band frequencies (18–27 GHz) for high atmospheric attenuation. It has a maximum unambiguous range of 20 km and altitude coverage from wavetop level to a height of 8,000 m to detect vertically plunging threats in the zenith and low altitude threats close to the horizon. Using a rotating antenna located in a spherical radome atop the pedestal mount it mechanically scans 360° in azimuth at a rate of 60 rpm and -10° to +55° in elevation with multiple electronically steered beams. On engaging a threat the surveillance radar assumes automatic slew-to-target control of the pedestal azimith and elevation drives to lay the Xiphos' missile launchers, engagement radar and optronic tracker (described below) on to the target bearing.
The engagement radar is a linear frequency-modulated interrupted continuous-wave (LFMCW) radar operating at M-band frequencies (60-100 Ghz) that combines target tracking, missile illumination and datalink functions on a single aperture. It uses a co-axial fixed (non-rotating) planar antenna that employs digital beamforming to instantaneously cover a 90° sector with a pattern of multiple electronically steered pencil-beams. It has a maximum unambiguous range of 30 km and can perform reflection-free tracking down to wavetop height. Capabilities include automatic hit point correction, splash reporting and kill assessment.
In an engagement missiles launched from the Xiphos platform are gathered in to the line-of-sight of the surveillance radar and handed over to the continuous wave engagement radar that simultaneously tracks and illuminates the targets and missiles. The fire control system computes and transmits guidance commands to missiles using fire control quality track data correlated with bearing and velocity information transmitted from missile seekers to improve the guidance accuracy and resist jamming, decoys and clutter. The surviellance radar can simultaneously track up to 100 targets and prioritise from up to 50, and the engagement radar can simultaneously illuminate 12 targets and control 2 missiles per target for a total of 24 simultaneous interceptions.
Terminal phase guidance of hittiles and guided projectiles is handled by on-mount optronics directors that provide undetectable and unjammable cues to both guns and missiles as well as providing low altitude surveillance, detection, recognition and tracking, and closed-loop fire control. The Dory CIGS and Xiphos ILMS are each equipped with a unit containing a multi-channel ballistic computer and integrated day/night all-weather passive electro-optical/infra-red (EO/IR) sensors that combine TV and thermal imaging channels, laser rangefinder and laser-beam missile guidance channels. The Xiphos director is mounted coaxially on the pedestal where it can only traverse the azimuth and elevation limits of the weapon mount. It contains a wide-angle forward looking infra-red (FLIR) camera, wide field-of-view (WFOV) colour daylight continuous zoom CCD TV camera and laser spot detector, narrow field-of-view (NFOV) low-light level continuous zoom electron-multiplied CCD TV camera, and two low power pulsed UV laser emitters. The Dory director is mounted on the roof of the gun house on a independent three-axis gyro-stabilised automatic slew-to-cue turret mechanism that can traverse 360° in azimith, and +90° and -30° in elevation. It consists of a lightweight sensor head with large aperture optical system containing a dual-band FLIR camera, colour daylight and low-light level continuous zoom CCD TV cameras and dual UV laser transmitters with opto-receiver tracker system. All optics are protected behind polycarbonate windows and thin-film-coated laser protection filters.
In combination with own-ship/off-mount sensors and digital signal processing each system is capable of automatic sector surveillance, automatic target recognition, automatic target tracking and automatic target designation. Capabilities include computer aided optical tracking against evasive maneuvering targets, multi-target tracking (MTT) of up to 100 targets at ranges up to 18 km, and target prioritisation and kill assessment functions. Each FLIR camera is based on a two-dimensional staring-type focal plane array (FPA) that stacks large format (640×512 pixel) galium arsenide (GaAs) quantum-well infrared photodetector (QWIP) thermal imagers with a broad spectral response in either 3-5 µm medium wave infra-red (MWIR) wavelengths to detect hot targets such as airframe heating and jet pipes, and 8-12 µm long wave infra-red (LWIR) wavelengths for recognition of cool targets such as stealthy vehicles. Using dual-band imaging or TV/FLIR sensor fusion it can operate in poor visibility and degraded weather conditions and against high optical clutter (e.g. high seas states, haze, smoke) when tracking low-level targets. Boresighted to each camera system is the laser tracking system that provides beam-riding guidance to missiles and gun-launched guided projectiles. Each laser transmitter unit has two diode-pumped solid state (DPSS) laser emitters using frequency-doubled gallium arsenide (GaAs) laser diodes to pump a neodymium-doped yttrium aluminium garnet (Nd:YAG) crystal to produce 380 nanometre (nm) wavelength UV light, and highly sensitive wide dynamic range four-quadrant photodiode optical receivers. Operating at a high pulse repetition frequency (PRF) of 25 pulses per second (25 Hz) each laser transmitter can illuminate a dozen targets simultaneously at ranges up to 10 km with a high line-of-sight stability for extremely precise firing accuracy of the lasers.

Manticore C-RAMM system.
The Manticore C-RAMM (Counter-Rocket, Artillery, Mortar, and Missile) system is a land-based, modular, quick reaction, fully autonomous, hybrid gun/missile-based low-level air defence system that provides point defence to fixed sites and ground manoeuvre forces from indirect fire and guided munitions. It has the same day/night all-weather and low signature sense and warn capabilities as the naval Manticore weapon suite, using the same self-contained weapon mounts with servo-controlled turntables, acquisition and tracking sensors and closed-loop fire control systems.
A Manticore C-RAMM system combines one or more independent firing units, either a complete Dory Close-In Gun System with optronics director and/or a complete Xiphos Inner Layer Missile System with ready-to-fire missiles in launch canisters, K-band surviellance radar, M-band engagement radar and optronics director. Targets are engaged by hittiles or cannon-fired CTGP rounds with tungsten dart projectiles that can defeat the hard carapaces of mortar and artillery shells. Changes compared to naval Manticore include an auxilary power unit (APU) to operate the electrical system, updated software supporting launch point calculation, impact assessment of incoming fire, enhanced ground clutter rejection filtering, and compatibility with battlefield management systems such as Lyran Arms Cromwell II, LAIX Arms Warrior III and Synergy Electrodynamics Cornerstone, and the addition of a 66-channel all-in-view tracking GPS receiver module and Wireless Audio Voice Emergency System (WAVES) that automatically broadcasts audible alerts over a tannoy to warn nearby personnel to seek protective cover during an engagement.
Tactical road mobility is provided by a 8x8 high mobility heavy duty truck or semi-trailer equipment transporter with a payload capacity exceeding 10 metric tonnes. The system is compatible with any prime movers equipped with fully-automatic hydraulic jack automatic levelling systems, including the hybrid-electric Oshkosh HEMTT A3 and LAIX/Lyran Arms LALY-1100 Novitas in service respectively with the armed forces of Etoile Arcture and Lamoni. A weapon system can be mounted with anti-vibration cushioning on the rear bed of any suitably modified truck to provide mobile protection that can keep pace with forward deployed forces; or on a special trailer towed or air-transported to a semi-permanent emplacement to defend forward operating bases, logistic hubs and high value installations from hostile artillery, rocket and mortar fire.
As with naval Manticore, land Manticore can be operated stand-alone or integrated into an overall air defence system which provides increased surveillance volume, and shorter warning, reaction and engagement times. Integration with a air defence cell or battery can either be by Ethernet 10 mbit/sec fibre-optic networks and/or secure two-way UHF radio datalinks. Machine-to-machine middleware enables full plug-and-fight interoperability with numerous assets including counter-battery and target acquisition radars (e.g. LAIX Arms LA-135 Cutlass Firefinder Radar and Lockheed Martin AN/TPQ-53 Counterfire Radar System); coordination from a centralised fire direction centre (FDC) that generates the local air picture and provides precision track data and engagement orders to firing units; and missile-based C-PGM (Counter-Precision Guided Munition) capable systems (e.g. Sequoia Dynamics M84 Argus Forward Area Air Defence System and LAIX Arms LA-425 Bestia Tactical Air Defense System) that add an upper tier of defence against guided bombs, anti-radiation missiles, tactical missiles and cruise missiles.
