Common European Space Agency Cruiser


By Bryn Monnery, Laurent Esmiol, David Gillon and D Hebditch




The Common European Space Agency Cruiser, or CESAC, followed on from the success of the pan-ESA Kiev Class Destroyers or CESADs. The CESACs were to be heavy combat warships a role they fulfilled more than competently for its time although it proved to be less capable of evolution than its lighter counterpart. Although superseded by more modern types in the service of first line powers they have served a glorious swansong with the Ukrainians at Eta Bootis. 




The concept of the Konstantine as a common European design is by David Gillon. Artwork is by Laurent Esmiol.

“She’s gone sir. All broadcasts ended. Kafer ships pulling away from Aurore orbit. She’s dead sir.”


The news, delayed by the vicious rearguard action the Jeanne d’Arc put up, hit Borodin hard. It was the final straw, a litany of defeat that tasted like ashes, eight warships gone and now hundreds of Frenchmen dead on the wreck of one of humanities most modern and powerful ships. Much worse would surely come for the colonists of Aurore.


Now only a pair of frigates and Borodin’s badly battered Konstantine remained of the powerful human fleet and they were fleeing for their lives. Deep inside her hull damage control parties worked to save the ship and bring internal fires under control. Already several of the ship’s crew had died in the attempt.  


Borodin had pleaded with his French colleague to fight the aliens away from Aurore, deep in the Eta Bootis system. However the Frenchman was still scarred by memories of the outmanoeuvring of a powerful French squadron at 61 Ursae Majoris by a motley group of Manchurian and Elysian privateers. He was staying close to Aurore at all costs…


These were not privateers, or raiders, but massive alien warships of the line and they’d obliterated all that the humans put in front of them. There had to be a better way to fight them Borodin was sure of it. All he had to do now was survive and get the Konstantine to Hochbaden. She was an antique by the standards of the sleek, modern French cruisers but she was all he had. She’d kept him alive so far.

Development History


The CESAC programme developed directly from the success of the preceding CESAD programme and followed the same general principles. Economies of scale would be gained by producing a single class of warships for several nations. Once again the French and Ukrainians led the way in pushing for the programme; the Ukrainians would once again gain the honour of launching the first ship of the class whilst the French took the lion’s share of the design work.


At the time most of the major starfaring nations key cruiser designs dated from the era of the 2nd Rio Plato War and were now around three decades old. In the time since the concentration had been on smaller, more versatile warships, now most nations recognised their key combat ships needed upgrading.


The CESAC was designed to be a ship which could be the core of a fighting squadron and be robust, and well armed. Its missile armament was designed to match those of the CESADs which would fight alongside it, but its direct fire armament was much greater. Screen technology from the Ypres Class would be used and similar armour to that of the CESAD carried.


At the time it was assumed that most of the likely heavy combats would take place in the Core systems the CESAD was designed to be a relatively small craft to avoid excessive spending on the expensive armour and screen designs. Naturally this would have a knock on effect when using the ship for long durations away from station facilities.


The CESAC construction methodology was very similar to that used for the CESAD with a modular approach taken for the space frame but key items such as the drives being produced centrally. Fitting out could be done centrally or at national yards and there was considerable flexibility in some of the minor detailing on the craft in addition to armaments.


The first CESACs were introduced into service with relatively few teething troubles, however it quickly became obvious that although it was an excellent ship for what it was designed for it had relatively little expandability due the small hull size. As a result while the CESACs remained in service for several decades there was to be no series of upgrades as with the CESADs. National upgrade programmes existed but most nations went for entirely new designs with their next generation cruisers, the French most notably with their Suffrens.

Design Characteristics




There were five key design characteristics for the CESAC design, many of which were shared with the . These were:


-         Common hull design using standard RT2 composite materials. Whilst the sections had to be cast in a special facility they could be assembled in almost any shipyard.


-         Modular approach to internal systems allowing individual nations room to customise avionics, sensors and other systems.


-         A heavy missile armament to maximise long range firepower. A heavy laser armament allowing excellent point defence and the capability to close and overwhelm opponents at close range.


-         Protection in the form of hull armour and shields developed for the Ypres.


-         A commonly produced drive system utilising a French Alsthom designed 200MW fission reactor and a purpose built Alsthom stutterwarp drive.      

-         Elementary force projection capability with up to 80 troops embarked and capability to carry three small craft for short durations.       


Hull design

The hull is composed of three distinct parts all of which are armoured. The hull configuration was quite advanced for its time and there are echos of it in the American Kennedy Class.


-         The bow contains the operational systems of the ship. Including the bridge, computers, TAC, sensors, stores, life support and weaponry.


-         Spin habitats which allow the ship to carry a significant number of crew in addition to a med bay. It contains area of recreational space.


-         The bulbous stern contains the fission powerplant and the stutterwarp drive. In addition the bulk of the engineering components and fuel is stored here. The numerous engineering crew work from here.


Overall dimensions:

-         Length: 85 m.

-         Tonnage: 12500 tonnes



The CESACs were initially produced with a very similar armament fit, although later refits have meant that remaining CESACs can be armed with a wide variety of weapons:


-         18 x Guiscard LL-55 laser weapons mounted in masked turrets.

-         9 x CESAM carried in three bays located in the bow with three remote piloting stations.



Sensor systems are provided by Darlan Opto-Physique and were developed from those used on the CESAD project.


-         Active with one working station:

-         DSAP S-2252. (Active: 10)

-         Passive with two working stations:

-         DSMSP S-2253T (Passive: 5)

-         Standard Navigation systems, Gravitational sensors, Deep system scanners.


Engineering Systems

-         Power Plant: Alsthom 200Mw fusion reactor.

-         Drive:   Alsthom Old Military 140MW stutterwarp drive.



The CESAC has a total of 197 crew:

-         22 in bridge

-         23 in TAC

-         30 in engineering

-         7 in medical bay

-         10 in steward section

-         80 ship's troops (9 normal compliment)
-         9 small craft (if embarked)


Living conditions in the CESAC are relatively spacious for a ship of this era, although it can become crowded when a full compliment of troops are embarked..

Service History




France purchased no fewer than six CESACs for service with the MSF as the Constellation Class. The CESAC emerged at a somewhat embarrassing time for the MSF following the dramatic cost overruns on the innovative Ypres Class ‘frigates’. These overruns had bitten into the procurement budget which the revolving door governments of the 12th Republic were unwilling to refill. The MSF were more than willing to accept a mostly French CESAC following the success of the CESAD.


The French CESACs were christened Herakles, Hydre, Persée, Cassiopée, Orion and Sagittaire. These were commissioned from 2262 onwards with the last entering service in 2271. The Constallations were widely deployed around France’s colonial holdings as well as forming a key element to the core fleets’ striking power.


The first Herakles was involved in MSF operations during the Canton-Indonesia War to escort merchant shipping moving from the core to the Chinese Arm from Indonesian space force and privateer operations. Famously the ship was involved in the capture of the Q-Ship privateer Brisbane Express in the last year of the war. All the ships saw service in similar operations during the 3rd Rio Plato War.


The Constellations were the backbone of the French cruiser fleet during the Central Asian War, supplemented by the first of the new Suffrens. Given the superior force projection capabilities of the Suffrens the Constellations saw most of their service in the core worlds and saw frequent combat against Manchurian raiders and blockade runners. The Cassiopée was destroyed by the Manchurian main force on the Chinese Arm in the last year of the war, an event which triggered a major MSF incursion into the arm.


The Constellations began to be retired following the Central Asian War, Herakles was scrapped and Hydre sold onwards. The remaining ships were retrained due to the rise in tensions with the German States, Persée was later crippled in an ambush by DSKM raiders in the outer Sol system. Efforts were made to salvage the ship, but she too was scrapped and the drive coils recovered.


Orion and Sagittaire remain in service with the French 1st and 2nd Fleets. They have been upgraded with new avionics and missiles and although due for retirement they have been kept on to allow the MSIF to send more modern warships to the front against the Kafers. It is not yet known if they will be kept on as more Vengeur Class cruisers are completed or if they will be sold on to a French ally, perhaps Freihafen, or simply scrapped.   




The RSN was rather more enthusiastic about the CESAC than the CESAD, at the time it was making do with the stately, if pedestrian Vanguard Class dating from the 2230s. The RSN’s development budget was tied up in the Dreadnought project and the Future Fleet Battle Ship or Revenge Class was some way in the future. For the RSN the CESAC was a cheap way to bridge a self evident capability gap.


The British purchased three CESACs commissioned as the Vian, Cunningham and Summerville. The naming of the CESACs was, like that of the CESADs, widely remarked on in the press. The RSN’s media operations team merely remarked that they were honouring oft overlooked WW2 commanders, although once again Parliamentary Questions were raised on the issue.


In RSN service the CESACs proved to be something of an acquired taste. Used to the long-legged Vanguards and Devonshires many RSN FBS crews decried the short range and cramped quarters of the CESACs. However several key captains championed the CESACs which were robust and capable of aggressive handling in a close in engagement and the ships became known as ‘bulldogs’ throughout the service. Like the French the RSN retained the CESACs mostly within their core based organisations.  


The Bulldogs saw service in operations to secure British lines of communication during times of tension and later saw service on the Chinese Arm at Clarkestar and Doris at the height of the piracy crisis in that arm of space. The British CESACs were paid off in the 90s as the King Christian Class began to enter service.



Azania’s purchase of three CESACs represented the acquisition of the largest and most powerful warships yet to see service with the Azanian Space Force. The Cape Town, Johannesburg and Durban were procured in the latter half of the 2260s and together with the CESADs formed the backbone of the ASF’s striking power for the best part of three decades. The lack of a real threat to Azania’s holdings saw the three ships placed in reserve and mothballed from 2295.


The Kafer War however caused a reassessment of the capabilities of the ASF and the Durban was reactivated in 2299 using parts form the other two. The Cape Town followed suit in 2301 using spares purchased from Ukraine. The Durban formed the key part of the Azanian reinforcement squadron to the French Arm in combination with a number of CESAD destroyers.   


Bavaria – Germany  


Bavaria bought strongly into the CESAC programme with no fewer than five CESACs being procured in two batches and named Husar, Uhlan, Kürassier, Schützen and Jäger. The BSM’s CESACs played a key role in Bavaria’s prosecution of the Central Asian War. To sustain the colony at Rho Eridani on the Chinese Arm the BSM was forced to dispatch substantial combat groups in order to ensure merchant convoys arrived successfully.


Initially the Manchurians only conducted harassing operations against the BSM but these ramped up substantially in 2286 when the Manchurian Main Force mounted a deliberate assault on a Bavarian resupply convoy resulted in the destruction of the entire convoy together with the destroyer Württemberg and a pair of frigates. This debacle resulted in an increasing scale of protection for convoys although in December 2286 a repeat Manchurian attack resulted in the loss of the modern Haupstadt and the Husar.


As a result Bavarian convoys were often coordinated with major French incursions into the Chinese Arm by the 5th Fleet and it was standard practise for at least two CESACs to escort each convoy. One of these missions resulted in the scuttling of the Schützen from battle damage following a desperate but successful rearguard action. The crew were rescued by the Manchurians and interned for the rest of the war.


 The loss of two CESACs and the impending obsolescence of the class caused some dissention in the higher echelons in the ranks of the BSM. Some commanders desired the purchase of some of the excellent French Suffrens whilst others looked to launch a rebuilt CESAC with modern avionics and weaponry. Consequently the Uhlan was withdrawn from service in 2290 and put through a huge refit and plans were laid for the other two survivors to be refitted too. The Germans however had other plans with their robust Hamburg Class and when Reunification occurred many systems destined for the CESACs were used in the Hamburgs instead.


Kürassier was stationed above Tirane and her Captain declared for Germany and set out for the Sol system and was subsequently destroyed by the French 2nd Fleet. Jäger and Uhlan survived the war but the former was retired in 2295 with components being used in the continuing Hamburg building programme. Uhlan remains in service but is used by the DSKM in a training role in the Sol system but can be retasked very quickly. Indeed Uhlan was dispatched to Neubayern prior to the Battle of Beowulf to act as a force of last resort.     




The Ukraine purchased three CESACs and was again the first nation to launch a CESAC. The idea was to have three CESACs to enable one to be permanently deployed to Eta Bootis in order to defend this expensive colonial effort and another be tasked to OQZ. The three Ukrainian ships were the Konstantine, 22nd of January and Zaporozhian.   


The ships first saw action during the Central Asian War escorting convoys along the French Arm and warding off Manchurian raiders and privateers. The Ukrainian 3rd Squadron, led by the Zaporozhian was involved in operations onto the Chinese Arm in 2286 and ’87 with the French 5th Fleet.


The Kafer War saw the Konstantine become one of humanities most famous warships under its commander Sergei Borodin. It was almost constantly engaged in action over the course of five years, being damaged on numerous occasions before returning to Earth late in 2303 to a hero’s welcome. The 22nd of January together with smaller ships led the 3rd Squadron, Ukraine’s contribution to the Reserve Fleet at the Battle of Beowulf and subsequently replaced Konstantine at Eta Bootis.


Ukraine has upgraded its CESACs throughout their service and intends to keep them in service although is looking to introduce a replacement class in the near future. Ukraine has a small but thriving business producing spare parts for various CESAC operators.     


Other Nations


The CESACs were somewhat less successful ‘second hand’ purchases than the CESADs, mainly as they are much more expensive to operate than their smaller cousins. However several smaller nations have operated hand-me-down CESACs or a small number of new build ships. Today there are less than a handful of these CESACs in operation.

Appendix 1 – Common European Space Agency Missile


The CESAM was developed almost in parallel with the CESAD and was intended to provide a heavy hitting strike capability. Prior to its development most missiles carried an energy weapon and were really remote weapons platforms.


The CESAM project was led by a British design team but included substantial input from Russia and France. Once finalised the CESAM was adopted by most of the nations who signed up to the CESAD and CESAC designs, although under different names. It is known as Silka in Russia, and Selkie in the UK, while in France it was known as the DA-2260 and supplemented the Ritage-1. Although now obsolete and replaced by more sophisticated designs in the leading militaries examples of the CESAM and its derivatives are still in service with many space forces.
