Background:
The Beausejour class was conceived to fill a gap in the Marine Royale's fleet for a need for a cheap, small, general purpose escort and patrol ship. Intended to be built in large numbers and employed for trade protection, merchant and fleet escort, training, and other duties. In 1972 the Marine Royale commissioned a design study for a light, under 20,000 tonne displacement, fleet carrier able to operate light fighters or anti-submarine warfare aircraft at the lowest possible cost without sacrificing utility or safety. The result was the design which came to be the Beausejour class. The first ship was laid down in Halifax in 1978 and commissioned after her sea trials in 1981 as the PA Beausejour.
Design:
The Beausejour class is designed with minimum cost for highest utility as the prime aspect. The study concluded what the minimum deck needed to operate the S-2 Tracker, the primary ASW aircraft of the Marine Royale. The flight deck was designed around this with an added safety margin. Simultaneous landing and launching operation was abandoned for cyclic operation as the primary role was to sustain a patrol.
The Beausejour class is built to merchant standards, in civilian yards to cut costs. It is intended to be quickly replaced as needed. In addition to this electronics, weapon systems, and other elements are minimal. The Beausejour has an air search radar and navigation radar set only to a level required for its own operations, and virtually no self defense armament. It is reliant on escorting destroyers for defensive systems. The most complex systems are those needed for flight operations, which are operated from the carrier. She does not posses flag capabilities, and is unable to be used as such in more then a severely limited patrol fashion in peace time.
Due to being built cheaply and to merchant standards, the Beausejour class have been criticized for their poor damage resilience. One incidence involving the collision between the Pubnico and a civilian fishing trawler. The Pubnico had to be towed back to Meteghan for repairs in dry dock lasting six months. The Marine Royale has defended the design of the ships as being adequate for their intended role as cheap escorts that are relatively expendable in wartime. Indeed, each ship costs approximately $360 million to produce, one sixth the cost of the 45,000t nuclear attack carriers of the Beausoliel class.
The Beausejour class are intended primarily for mass production. The ships are produced at two yards in Acadia. Theriault Shipyard of Meteghan and Neiforth Shipping in Chezzetcook, with the first two ships of the class being built in Halifax Shipyard. It takes approximately three years from keel laying to commissioning of each ship of the class. The ships were commissioned one per year starting in 1981. The latest of these ships, the PA Ecum Secum was commissioned in Musquodobit Harbor on April 19th, 2011.
Powerplant:
The Beausejour class is powered by combined steam and gas. It has four White Steam Boilers providing primary power and power to the steam catapult. In addition two LM2500 gas turbines are included to provide boost power for flight operations as needed. Propulsion is provided by two shafts running fixed pitch propeller blades.
Aviation Facilities:
The Beausejour class has an angled landing deck of 8.5 degrees with three arresting wires. The deck is able to accommodate deck parking on the starboard bow, with catapult and landing areas overlapping.
The catapult is a single 50m long CP-79 steam catapult which is capable of launching loaded Trackers and Tracker-derived aircraft, as well as the F-2H Banshee jet fighters then ending their operation with the Marine Royale. Its capabilities were a driving factor in the navalization of the F-5 program to replace the F-2H.
The hangar is large enough to accommodate two squadrons with ease and maintenance capability, or to overcrowd with more. It is capped at either end by the inboard lifts, with an additional space aft of the aft lift for stowage and maintenance work of aircraft components removed from aircraft.
Armament:
The Beausejour is fitted with three armament systems. Two 40mm Fast Forty close in weapons systems, and a single eight round launcher for the Sea Sparrow missile, all located on the island. These systems are provided with a single fire control radar unit and intended for backup use only.
Embarked Aircraft:
The Beausejour class is intended to be a fleet and patrol escort ship, with no permanently assigned airwing. Squadrons of the Aeronavale are rotated through the various ships on a regular basis instead. The Aeronavale is responsible for the majority of Acadian home island air defence and patrol, and as such squadrons are rotated between ship board deployments and their home airfield on land as active duty. The only aircraft permanently assigned to each Beausejour are the two Eurocopter Panther utility helicopters which provide plane guard and search and rescue duties, and the two E-1T TurboTracer early warning aircraft.
The Beausejour class is equipped to support on a regular basis three squadrons of aircraft, with four being the maximum capacity war load for short periods. Normal aircraft groups will vary depending on mission, however the most common aircraft employed are the F-20N fighter and the S-2T TurboTracker ASW aircraft. With up to 24 fighters or 18 Trackers being carried in normal load. Outside of exercises a full load of trackers is almost never carried, with full fighter or a mixed group being more common.
Crew Accommodations and Safety:
The ship is designed for a crew of six hundred, with an air group of three hundred and fifty. The ship is equipped with central air conditioning and heating. Provisions are for nuclear biological chemical protection, however beyond deck cleaning no systems are installed, leading to a lack of NBC protection. Fire protection is exceptional however, especially from Mavillette on.
Ships of the Class:
Thirty-two ships of the class have been built, out of an authorized forty. Forty ships were authorized in 1979 so that the final ship of the class was coming into service just before the first ship would be decommissioned if peacetime service would be continued. The final eight ships were delayed with the 1998 acquisition budget, and finally canceled in 2008.
The thirty-two ships of the class are all named for locations within Acadia. Most are named for important French settlements, however several English as well as Native locations have given their names to ships of this class, as well as the most prominent black community in Acadia.
The names of the ships are as follows. Numbered starting with 11 on Beausejour and continuing to Ecum Seacum at 43.

TL:DR, modern build Majestic class with lots of upgrades built in, design based on final Minas Gerais form. With a bit of Dedalo or whatever it's called thrown in (COSAG). Very limited form, intended to be built in lots (For sale on SMS btw) from civil yards. Intended to operate 12 trackers, four F-20s, and three Helos. Which is something I understand the Bonnie could carry (Replace F-20s with Banshee that is) on her space. Helos are Dauphine, so they are not that big.

Secondary Mission:
- Amphibious Warfare Role
The Beausejour class was also designed with the role of amphibious warfare as a secondary role. Because of the numbers required by the Marine Royale, the number of amphibious warfare ships was limited. To maintain the ability to place a landing battalion of naval infantry anywhere on short notice, this capability was designed in. To accommodate this without drastically increasing size or decreasing the aviation capability was a difficult concept to approach. The result however, proved to be simple.
As originally designed, the port side of the hangar was fitted with lock down points for six meter ISO containers. The Marine Royale had previously studied using ISO containers as part of their sealift, to make use of merchant shipping in a time of war, and the idea of using these containers for barracks was nothing new. Eight meters of the hangar are taken up along the port side length, not interfering with elevator operations. Although this reduces aircraft capacity and flow, as well as forces maintenance operations to be moved in the hangar, it allows the carriage of three stacks of fifty containers, one hundred and fifty total, which act as a wall to isolate the barracks area. Each container is equipped with twelve bunks and a small storage space, with a few amenities. This allows a theoretical capacity of one thousand eight hundred troops with only a 25% reduction in hangar area, and no disruption of elevator operations. In practice, however, berthing is provided for 900 troops, the air landing portion of a battalion, including recreational, mess, and command areas.
The containers can be shipped as normal ISO containers, transported by truck, and removed from the ship with little difficulty and transported by helicopter to establish shore bases.

The Beausejour is fitted with three armament systems. Two 40mm Fast Forty close in weapons systems, and a single eight round launcher for the Sea Sparrow missile, all located on the island. These systems are provided with a single fire control radar unit and intended for backup use only.
Embarked Aircraft:
The core of the Beausejour class is its aircraft. An effective air group was determined in the 1972 study the gave birth to the Beausejour. In that study the Marine Royale determined that a force of twelve high-endurance anti-submarine warfare aircraft, in this case the S-2 Tracker, would be able to provide twenty-four hour patrol of four aircraft allowing maximum saturation of an area. A half squadron of F-2H Banshee fighters was stipulated, to be replaced with the result of the Follow On Naval Fighter Project, which would result ultimately in a navalized F-20 Tigershark. Rounding this out would be a single carrier on board delivery aircraft and two airborne early warning aircraft, plus three utility helicopters. It was determined that this would be the most efficient air group to perform outer-ring anti-submarine warfare, with the inner ring being the realm of escorts.
In 1980 five squadrons were assigned to permenant duty on the light carrier fleet. These included two anti-submarine squadrons, 711 and 747, one fighter squadron, 840, one helicopter squadron, 931, and an Airborne Early Warning squadron, 691. These were used to form the backbone of the first two Air Regiments assigned to Beausejour and Grand Pre, assigned pennant numbers 11 and 12 respectively. The first of which, designated 11 Aeroregiment Beausejour embarked on the Beausejour on October 9th, 1981. It was formed of the following:
11 Aeroregiment Beausejour:
- 711 Anti-Submarine Squadron
- 11/840 Fighter Detachment
- 11/931 Helicopter Detachment
- 11/691 Airborne Early Warning Detachment
In 1988 900 series squadrons were amalgamated into the 600 series squadrons as composite squadrons called Fleet Support Squadrons. These squadrons were then reassigned to the different fleets to provide two squadrons and a detachment per light fleet carrier. In 1989 Beausejour's airgroup looked like such:
11 Aeroregiment Beausejour:
- 711 Anti-Submarine Squadron
- 637 Fleet Support Squadron
- 11/840 Fighter Detachment
Embarked aircraft included twelve new-build S-2T Tracker ASW aircraft of 711 squadron, six F-20N fighters of 840 squadron, two E-1T Tracer AEW aircraft, one C-1T Trader COD, and three Eurocopter Panther helicopters. This format would be followed through the rest of the fleet of thirty two ships.

Updated the first post with the most recent version. Bringing back the 1942 light fleets for modern usage.
Literally intended to be a numbers ship, it has little utility for strike. The air group is derived from what HMCS Bonaventure actually carried, and is based on it. Rather then 12 Trackers, 12 Banshees and four helicopters, it's 12 Trackers, three Tracker-based airframes, six Banshee sized fighters, and three really small helicopters. I figure I can realistically presume a cost, at mass production, of around $400 million each. Equipment for doing anything other then air ops is minimal. Very minimal, to the point of not being there. She has surface radar for navigation only, air search radar for local control of her air group, one search/track system for her minimal defensive armament which may likely change to even less, the needed communications equipment, and other needed stuff, and that's it. Her fit isn't much more complicated then HMS Ocean.

Might be changing this to STOBAR.
Speaking with some friends of my grandfather recently with my grandmother's passing last night, I have learned of a few proposals/studies/interesting documents on the idea of the Canadian Navy buying HMS Hermes in the 1980s, re-installing the arrestor gear and flying Trackers and CF-5s off them.
I have already read a proposal by Canadair to create a folding-wing naval F-5 for the RCN to fly off Bonnie. There is apparently one as a re-proposal to fly off a ski-jump equipped Hermes. Going to see if there is anything to this over the weekend and next week while I am in the area of the appropriate archives (RCN naval aviation archives).
Tracker and its siblings (Tracer and Trader) could fly off Bonnie full load without the catapult. Seen some home movies of them doing so taken by my other grandfather while sailing in the 1960s.

I keep flopping back and forth. Here's some thoughts on a history/development cycle.
Acadian navy starts the post-war period with a mix of Colossus/Majestics, an Independence or two, and a few former CVEs. A mixed bag, flying Seafires until 1950, and Sea Furies from then.
Here comes the fun. CVEs are the first ships to get a fleet upgrade, in 1948-1950, nothing seriously major. Then stood down (Placed in reserve) around 1955-56. Colossus/Majestics and Independence undergo major overhaul together over the 1950-1960 period to operate jets, as the Acadian Navy slowly phases out the Sea Fury for something capable (Considering Banshees).
By the early 1970s, the Independence/Majestic/Colossus fleet is cut to a fraction due to manning issues, and a small number of former CVEs are returned to service as interm patrol ships, with helicopters.
Early 1980s Acadian Navy makes a shift, following the British lead, to STOVL ships. By this point, very few CVLs exist, and they are slowly converted to STOVL. Maybe 1-2 CVE converted for training/testing and limited operational use. Sea Harriers ordered.
1985, new government, off-shore oil development, and economic boom brings the cost cutting to a halt. Half the fleet has been rebuilt/converted to STOVL, the other half is in bad shape. Sea Harrier orders are kept due to contract obligations, navy begins to fight tooth and nail to retain CATOBAR capability.
Mid-late 1980s, ambitious project to replace Independence/Colossus/Majestic fleet with local-built light CVNs (Like CdG) falls through, lower-cost option of dramatically-improved design based on the Colossus/Majestics followed.
First new ship (Beausejour) commissioned summer of 1994, barely resembles Colossus/Majestic, is essentially whole new ship. Reduced manning of new ships provides government contract for increasing number of CVLs in service to fill the needs of Acadia. CVEs kept in service, with one remaining at present, for training of STOVL fleet still in use.
And that's where we leave off.
Aviation wise, it's Seafire > Sea Fury > Banshee > A-4 (Early) > Sea Harrier > A-4 (Late)
By the 1994 commissioning of Beausejour, naval aviation is almost entirely Sea Harrier (FA.2 Standard), and A-4M (FA.2 Standard), and both need to be replaced. Domestic naval fighter program (Naval F-20!) started, with first aircraft delivered 2001 to replace A-4 squadrons one for one.
CATOBAR and STOVL CVLs being replaced on a one-for-two basis with new class. So is going slowly, as only one yard is building them.

Edit: Overall it looks like you have the history planned out fairly well. Are you planning on doing the same thing as you did with that Sumerian CVL, and make a drawing showing how aircraft go through the elevator, and to the catapults?
Sumer - January 6, 2012 02:49 AM (GMT)
Lol, how it switches, eh Yani?
And yes, the plan is the same. Using shipbucket though, and basing off a base-drawing. As this is, in many ways, an expanded Majestic.

It keeps moving around.
I'm at several options.
The two I'm considering are, for a roughly ~24,000t ship full load, $300-400 million per ship, lots of hulls, basic defensive systems, little else. Direct modern Majestic equivalent.
For slightly larger, to keep the same aviation capability but add weapons, a mini-Kuznetsov type battle carrier, but CATOBAR, to double as a cruiser and command ship, for roughly $1.5-2b per ship.
Now the problem in deciding the two is I have not decided how my escort forces are. So I am literally building two separate navies right now (In theory, to see how they would suit my needs) built around a core of battle carriers, and super-light escorts (Literally light corvettes), or around a core of light cruisers which escort the carriers, and FACs for everything else.
I'm bound by the need for 5 carriers minimum to maintain two up at all times.

I'm planning on joining SMS soon as a lower-end economy, and you'd have a couple orders from me if the cheaper option is available.

Super-cheap option.
Dropping the crew and re-working the berthing to be entirely 2-bunk and 3-bunk "cabins" that the Bonnie had for her officers and petty officers is pretty easy. New everything, much much much higher automation, and such. Repositioning a lot of stuff, and converting to an all-hands cafeteria/mess, rather then the enlisted mess and massive ward room for CPO and one for officers.
With reduction in space needs from the wardrooms alone, all crew berthing can be moved to decks 4 and 5, as can a large number of functions not related to aircraft. This gives me room to expand the hangar forward and aft of the current Majesic dimensions. This will alleviate some of the issues with a longer catapult, which will reduce hangar space.

Notes:
IC Catapult for lulz.
No steam needed. Conversion to entirely GT, meaning fuel bunkerage is common for all aircraft and the ship.
New propulsion systems mean lengthening one boiler room on the Majestic, and shortening another, total length freed up in the ship being 2m, plus 10m stretch being added midships. This includes an active stabilization system, but also more fuel and weapons bunkerage.
Ship is incapable of operating Rafale or Hornet due to size. Designed to operate A-4 and F-20 sized aircraft (I will produce a naval F-20).
CIWS and SAM are one each on the forward sponsons, for reference.
All internal space re-distributed. Should have same accomodation standards as the Type 45 and CVF. Even so, tonnes of internal volume freed up to move some things around, despite the enlarged uptakes and downtakes for the GTs.
Hangar greatly enlarged. Also new construction techniques and materials overall.
Rough cost estimates are:
- Less then $30 million annual operating cost not including airgroup.
- Procurement to cost around $250-300 million per ship.
- Expected service life to be 30 years.
Roughly $1.5 billion per ship over the course of their life including refits.
Aviation capabilities are not final, but she could embark three E-1 Tracers and 24 Skyhawks, plus two Seasprite sized helicopters.
Super-lulz light carrier of win. I will either sell it on NS or SMS, whichever I decide to be active in.

VLS on sponsons?
Might a box launcher of some kind be a better idea?

Mk.48 Mod 2 VLS will fit into 4.2m, which is the usable depth of a Majestic class sponson as wide as the Mk.48 Mod 2.
If I wanted to spare the 60 tonnes, I could have a total of 32 ESSM tubes.

There is some debate over whether or not VLS is suitable for carrier use. The Americans prefer trainable box launchers and the French and Italians full VLS silos.
IIRC the argument against VLS is that it disrupts the flight pattern over the carrier where as the box launcher method sends the missile out under it. Whether or not this is actually the case i couldn't say but i belive that was the case made against fitting the Gerald R. Ford with Mk41 silos.

For something the size of the Ford, it is a case that could be made. At this size, however, there is no choice. Few places are available that could take a box launcher without causing undue harm to flight ops.
Plus, at this size weight is an issue. And weight distribution as well. I'd rather fit 16 missiles in VLS and provide total coverage, then the 2-3 box launchers I would need to equal that.
Another option I had considered (And so have others) is the inclusion of a full length mk.41 style VLS in the island. A tactical length Mk.41 set of 16 tubes would have some absolutely hilarious advantages if the appropriate sensors were available. Unfortunately that turns my $300m carrier into a $500-600m carrier with air defence cruiser capabilities. Same could be done with larger Sylver launchers.
