DHM.1 Auk multipurpose helicopter drone, DHEW.1 Puffin airborne early warning helicopter drone (http://home.att.net/~brisbane-adams/qh-50catsea.jpg)

An early unchassised prototype model depicted.

The DHM.1 "Auk" is a multipurpose helicopter drone capable of performing anti-submarine and anti-surface ship operations, fire observation for naval artillery, over-the-horizon missile guidance, low-level real-time reconnaissance, and serving as a secure communications relay. With its search radar and advanced electro-optical sensor turret (low-light television, infra-red, and laser ranging), the "Auk" can also serve as a picket both against low flying aircraft and sea-skimming missiles and submarines.

The "Auk" can take-off and land autonomously and can be directed by friendly ships or helicopters onto submarine targets through secure datalinks simply by providing the drone with real-time sensor information: the "Auk's" laser inertial navigation and global positioning systems (INS and GPS) do the rest. The DHM.1 is able to use its radar warning receivers and short-range missile launch detectors to avoid enemy anti-air action.

DRA.1 Rook UMAV (http://www.eads.net/xml/content/OF00000000400004/6/26/517266.jpg)
The “Rook” is a multipurpose drone that may be launched from cruiser-sized helicopter landing platforms, aircraft carriers, or from ground stations. It is a very stealthy machine when flying clean on reconnaissance, missile guidance, or fire spotting duties, and carries such sensors and systems as synthetic aperture radar (SAR), enhanced electro-optical imaging, automatic target recognition (ATR), a secure global positioning system (GPS), inertial guidance (for those just-in-case situations), a Link 17G secure datalink relay. It can also play dirty by carrying up to four Hellfire or similarly sized missiles on four wing stations (six if two Stingers are carried for self-protection) and use its laser rangefinder-designator to perform light attack missions.

Cruisers or larger ships launch the “Rook” using a smaller version of the electromagnetic aircraft launching system (EMALS) used on the Royal Edmund-class carriers. This launching system produces an extremely small magnetic signature, less even than a colour television, so neither the launching vessel nor the “Rook’s” systems damaged. The Type 33L Tuesday helicopter landing system (which may be reconfigured to suit your navy’s specifications) guides the “Rook” in for landing, facilitating recovery in conditions up to sea state 4. The “Rook” recovers with an electromagnetic aircraft recovery systems (EARS) using two high tensile strength cables strung across the deck. Thrust reversers act to brake the DRA.1 even quicker. In case of missed cable, a lightweight mesh barricade protects both the “Rook” and the ship from most damage. Alternatively, the “Rook” can land on a Walmsley-class or larger aircraft carrier.

The Rook may operate somewhat autonomously using a pre-configured flight plan should communication with the ground control station (GCS) be lost, or should the GCS have to release control of the Rook. The DRA.1 can react to the environment using its various sensors (terrain following radar (TFR, use of which increases the radar signature), a radar altimeter, radar warning receiver (RWR) system, automatic self-defence decoy (chaff/flare) dispenser [OOC: a very small number are carried], GPS and laser-digital inertial navigation system (INS) and other systems) to alter waypoints to avoid or otherwise counter enemy anti-air threats (i.e. navigating around active radar sites).

The system can be used as a semi-autonomous attack platform on a preset flight plan, which is reconfigurable in flight to account for anti-air threats, using its automatic target recognition system (ATR) and identification friend or foe interrogator system (IFFI) to acquire and attack targets on its own. The ATR can be, if necessary, be updated by the GCS through direct link or by secure satellite communication link. The Rook can also return to roost autonomously using its GPS and INS should connection with the GCS be lost.

The Rook also can perform limited signals intelligence functions. The DRA.1 can receive signals data through its sensors and transmit that data to the GCS via secure datalink for processing on a dedicated data management system. The processed information may then be fed back into the Rook by the GCS to improve its survivability.

The manufacturers are moving towards developing a version with greater autonomy (the DRA.2), but it is still in the development stage.

Up to four Rooks can be controlled by a ground control station (GCS) or a tactical control station (TCS). A GCS is the size of a standard frieght container, but its functions can be distributed in a tactical control station (TCS) composed of two-HMMWVs (please note: trailers will be required to transport the Rooks to forward locations). Remote piloting of the Rook is assisted by a lightweight helmet-mounted head-up display and military-standard hands on throttle and stick (HOTAS) controls. As both the GCS and TCS use the same secure datalink, the electronic handover is both very easy for one’s own units to achieve and extremely difficult for enemies to disrupt.

DA.1 Tern UCAV (http://www.eads.net/xml/content/OF00000000400004/8/23/517238.jpg)
The "Tern" is the "Rook's" larger sibling and has approximately twice the weapons payload of the smaller UMAV. The "Tern" uses the same autonomous operation situational awareness module (AOSAM) as the "Rook." The AOSAM allows a drone control unit (DCU) to program in a generalised flight path that the drone may amend to avoid enemy air defences, or to attack high priority targets of opportunity as indicated by its automatic target recognition (ATR). Both the ATR and the "Tern's" mission profile may be updated in flight.

The "Tern" is able to carry three 250kg bombs or comparably sized weapons in three internal weapons bays (approximately 2.8 m long, 30 cm wide, 30 cm deep) for up to 1400 km, or greater with either external or conformal fuel tanks.

DSM.1 Squid autonomous underwater vehicle (AUV) (http://www.ise.bc.ca/images/explorer.gif)

The DSM.1 (drone, submersible, multipurpose) Squid is the RINN's standard submersible drone. The "Squid" may be launched either from its parent submarine's drone housing (RSIN vessels purchased with the "Squid" have these housings) or may swim out of a standard RINN (585mm) or larger torpedo tube. It is powered by high-efficiency fuel cells driving a high-power electric motor. With its clean hydrodynamic shape and quiet propulsion, the DSM.1 is very silent when it needs to be. The "Squid" is a modular design that can be configured to complete several missions. In its most common configuration, it has a module containing three noisemaker/torpedoes (NT module or NTM) that may be used to defend the submarine from enemy attack or may be guided by the DSM.1 to perform a limited assault. The explosive NTs travel at about 6 knots and are equipped with a small sonar seeker head. Alternatively, the "Squid" may carry a 20mm cannon firing supercavitating rounds (SCRs; up to fifteen carried). Generally the "Squid" travels at between 3-5 knots, although the DSM.1 can shoot off at a short-range burst speed of 20-25 knots when threatened, clouding its wake with NTs.

The "Squid" serves as a marine mine detector/neutraliser and as a short range sonar probe. In the former mission, the "Squid" may either be controlled by an operator via fibre-optic microcable (FOMC) or operate autonomously using its Lyme & Martens patented "Kingfisher" automatic target recognition system (ATR) in conjunction with its short-range pinpoint active sonar to locate mines. When the "Squid" detects a mine, it may attach an explosive device using one of its three explosive NTs to neutralise the mine. The DSM.1 may guide the NT to the mine by FOMC or via the AUV's acoustic-acoustic modem. Alternatively, the DSM.1 may use SCRs to detonate the mine. (Needless to say, exploding a mine would reveal the presence of the submarine.)

As a remote sonar probe to deliver real time intelligence to the parent submarine, the "Squid" trails a length of fibre-optic microcable (FOMC; up to 5 km contained within the "Squid") to transmit the drone's sonar data to the parent submarine for processing. If some rapidity is required (up to 25 knots on a straight course) or if the "Squid" is to remain on station for an extended period of time, a thicker power umbilical, which also serves as a towed array, to the parent submarine can be used so as to not drain the "Squid's" fuel cells and battery. The umbilical also serves as a towed array. (Umbilical option only available on RSIN built ships with drone davits.) Alternatively, the "Squid" can be sent out to autonomously map sensitive areas or to gather other intelligence such as enemy fleet dispositions. The DSM.1 is guided by its advanced inertial navigation systems and its short-range collision avoidance sonar.

An autonomous "Squid" may communicate with its parent submarine via an acoustic-acoustic modem. This communication system also allows the DSM.1 to return to its housing for debriefing. At great distances, however, the "Squid" may home into a particular sound signature emitted from the parent submarine. This sound signature beacon uses slightly modified calls of resident sea creatures, which may be updated in the field to fit circumstances, allowing the parent submarine and the DSM.1 to remain undetected.

GWS.41M Loon (http://www.worldweapon.narod.ru/image/shema3m51.jpg) [fig.2] (http://www.mbda.net/test_phototheque/photos/milas_2.jpg)
Figure 1 shown is an early preproduction version, whereas figure 2 indicates an early production model.

The "Loon" is an anti-submarine missile that can be launched either from surface ships or submarines. It carries 200-350kg lightweight (i.e. 324mm) torpedo (LWT) to the last noted position of the target before releasing its payload.
(Please note: wire-guidance of either the missile or torpedo is not possible with this system. Apologies for any confusion this omission may have caused.)

The weight of the launch vehicle, with booster but without the torpedo, is about 500kg (497.94kg; 376.71kg without booster). With an MU 90 torpedo, the Loon can attain a range of up to 60km, with an initial speed (ballistic phase) of up to Mach 2.25. The launch vehicle can be continuously updated by the firing vessel while in flight. Once the booster engine has been detached, the Loon cruises to the target using a high efficiency turbojet engine at trans-sonic (high subsonic) speed. Above the target, the launch vehicle releases the payload, which then parachutes into the water and proceeds to seek its foe.

The Loon can be launched by a ship equipped with a Mk.41 VLS, or a ship or submarine able to fire a Tomahawk missile.

GWS.47 Robin (http://www.globalsecurity.org/military/systems/munitions/images/smalbomb.jpg)

The GWS.41 "Robin" is a small diameter bomb designed to penetrate deep targets with precision, power, and the absolute minimum weight. Measuring only 1.83 metres in length and 15.24 centimetres in diameter, this 115 kg device can crack through two metres of reinforced concrete with its armour piercing steel casing, something which required 908 kg bombs previously.

Using its anti-jam GPS targetting system, the "Robin" can correct its attack autonomously once dropped. The "Robin" may be dropped as far away as 24 km from the target with a minute circular error probable (CEP; i.e. potential miss radius) of three metres, or twenty-six metres CEP if only the small three-axis laser INS is operable.

The GWS.48 "Starling" is a miniature smart missile that uses laser detection and ranging (LADAR) with improved low visibility performance along with an anti-jam GPS and small laser INS to search an area for targets of opportunity. Its autonomous target recognition (ATR) software will then prosecute the target and select the best warhead mode for the target. Like many advanced AI weapons, this weapon's effectiveness is greatly improved when working as a flock.

GWS.50 Pigeon (http://www.lockheedmartin.com/data/assets/4552.jpg)

Test model. (http://www.astronautix.com/graphics/t/tacitrai.jpg)

The "Pigeon" is a small, lightweight UAV designed primarily for single-use search-and-destroy missions.

The "Pigeon" possesses lightweight electro-optical sensors (light-intensification and infra-red) and an advanced passive radar/signals receiver and initial processor (radar warning (RW) and direction-finding (DF)) to identify its prey. An identification friend or foe (IFF) aerial runs along the belly of the drone to avoid attacking friendlies, while the secure Link 17G data link ensures that a human can be kept in the loop just in case.

Should no enemy signals be detected within the pre-programmed zone of attack or interest, the "Pigeon" can loiter. The area of interest can be altered in flight either by a control station or by the drone itself if it should pick up enemy signals within its range. (The "Pigeon" can estimate the fuel required to reach a target using a mote.)

Characteristics
Functions: real-time reconnaissance and attack aerial vehicle
Dimensions: length: 2.31m; diameter: 0.275m (housed); wingspan: 0.82m (deployed)

GWS.52 Pelican anti-ship missile (http://homepage.eircom.net/~steven/images/noranti.jpg)

The GWS.52 "Pelican" was developed by Lyme and Martens Aerorobotics to replace the GWS.39.3 "Jewel" (Yakhont-3) in domestic service.

The "Pelican," like the "Pigeon" is really a one-way drone with many advanced features allowing it to evade most missile defences as it approaches its targets. Like its siblings the "Rook" and the "Tern," the "Pelican" possesses an effective autonomous operation situational awareness module (AOSAM) permitting the missile to alter its flight characteristics and use active jamming (ECM) to counter enemy threats as well as to respond to countermeasures (ECCM), thus giving the "Pelican" a greater probability of successful strikes.

Like the GWS.39.3, the GWS.52 can work individually but is even deadlier in flocks. With its Link 17G.2 secure data link, the lead "Pelican" operating at altitude can communicate with the other missiles in the flock to assign and prosecute targets ensuring a wider range of strikes against enemy ships. With this data link connection, the "Pelican" can attack from various angles, regulating its thrust to ensure either a staggered or unique arrival time in the target zone. Furthermore, the data link permits attacks to be performed in conjunction with other combat drones, such as the "Puffin" or the "Rook," to minimise probability of intercept. For instance, the "Puffin" or "Rook" can use its search radar to illuminate the enemy fleet allowing the entire flock of "Pelicans" to remain below the enemy radar. Also, "Pelicans" and "Pigeons" can engage in a combined assault against a hostile fleet: the "Pigeons" eliminate the enemy's air defences while the "Pelicans" advance towards their targets.

When air launched from high altitude (10-15 km), the "Pelican" may initially proceed to target at 10-12 km altitude until its radar warning receivers begin detecting hostile emissions. The "Pelican" then descends to between 20 m and 5 m and accelerates towards its targets. From about 50 km away, one missile (if in a flock) ascends to acquire targets and transmits this data to the other missiles as it descends. This hi-lo profile and the "Pelican's" supercruise turbo-ramjet engine allows a maximum range of 825 km, slightly more than a BGM-109D TLAM. When either air launched from low altitude, or surface or submarine launched, the "Pelican" may opt for a lo-hi-lo attack profile, allowing attacks from as far away as 600 km. The "Pelican" may also perform a direct lo-lo assault. Using supercruise, the GWS.52 can prosecute targets from over 325 km distant, while operating at full speed (Mach 2.5) the "Pelican" can travel up to 240 km to its prey.

All in all, the GWS.52 offers a great advance in the field of modern naval superiority.
