Peru: Seeking Submission for CVL(s)

Peru wishes to solicit bids for possible sale of one or two new or used light aircraft carriers.

Requirements:

Size: Ideally not more than 20,000 t light, and sized to fit existing Peruvian infrastructure. Sufficient deck length to operate torpedo-bombers.

Speed: Min. 30 kts, preferrably 31-33 kts

Protection: CL-scale belt armor, reasonable deck protection against aircraft ordnance.

Airgroup: Minimum 24 A/C, with adequate size for projected aircraft growth rates.

Possible Transaction Components:

-If the carrier(s) is/are new-build, to be laid down by vendor in 1942.

-If the carrier(s) is/are existing, to be received 1942/43.

-In either case, a basic carrier orientation program, with crew and pilot exchanges to the vendor's fleet, would be desirous to facilitate effective start-up of the Peruvian carrier program.

Please transmit quote and questions to the Peruvian Ministry of Defence.

Proposal to Peruvian Ministry of Defence

Submitted for consideration for export sale

If ordered in the 1st Quarter of 1942 (assumed date of keel laying 1 Jan 1942) the vessel would complete in the 3rd Quarter of 1943 (assumed date 25 Jul 1943) and complete trials in the 1st Quarter 1944 (assumed date 21 Jan 1944).

Sufficient slip space exists in German shipyards to construct the vessel in the timeframe proposed (in point of fact sufficient slip space is available for a second vessel if desired)

Training of crew and aircrew can be accommodated within the current Kriegsmarine training programme.

You've already half-paid for one

Russia did a deal with a previous Peruvian government for a conversion of a collier to a light carrier. Peru stopped paying in 1936, and the RF Navy completed her in 1938 to free up the drydock. She's been an aircraft carrier tender/aircraft transport ever since. Peru paid a total of 2,500 tons, and there's 2,266 left to pay, plus a negotiable fee for occupying a drydock for a year and a half. Stats below:

The Peruvians forfeited that ship to Russia during the 1937 war, didn't they? If memory serves, the Colombians and Chileans both offered to pay off the remaining balance of the ship to keep it out of Peruvian hands. In any case, that deal was made prior to the war, and Chile will probably be rather cross if their ally gives a carrier to Peru now. :P

"The Peruvians forfeited that ship to Russia during the 1937 war, didn't they? If memory serves, the Colombians and Chileans both offered to pay off the remaining balance of the ship to keep it out of Peruvian hands."

RF yards have a reputation for commercial reliability to maintain, and RF government made it clear that Peruvian gvt have first dibs on her.

"In any case, that deal was made prior to the war, and Chile will probably be rather cross if their ally gives a carrier to Peru now."

Then they'll really dislike the idea of Russia selling a Grengam.

Though I think the price just went up, if only to profit even more since the Peruvians may see an opportunity to sow discord in FAR.

I wondered what that tonnage had gone for. Now I know and will have to think about what to do about that.

Monday, November 14th 2011, 6:48pm

Frankly, I thought we'd determined when we worked out the story of the war that Peru had forfeited the tonnage, and Russia took ownership of the vessel; so I never mentioned it or went back to discuss it after the war. The rest of FAR has Peru on their will-not-deal-with list, so I guess I presumed the Russians did too.

Provided the Russians were able to extort a sufficiently lucrative payoff and did not sell any electronics gear (or train the Peruvian deck crews), Chile would likely restrain themselves to some grumbling in the annual FAR conference and not much else.

(Please note that my protest is IC and not OOC.)

Atlantis would make an offer, if not for that nasty business in Colombia a few years back so they politely keep quiet on the matter. Colombia certainly would not be amused and would certainly would have pushed to limit peru from building certain ships post war.

OOC, talks to that end where suggested but never went through so I'd assume that if that were to remain the case, and I don't want to limit new players (both Alvama and Rocky took over post war) I'd assume that Iberia pushed to have no such limits placed and that Atlantis and Iberia convinced Peru to play nice and assured Colombia that future conflict would be swiftly headed off. I'd also assume Peru had a drastic leadership change to aid in that placation.

The vessel is designed to carry 48 a/c (4 squadrons of 12 each) for 2304 tons of misc weight. 196 tons can be used for spares, special equipment, electronics, staff facilities or growth reserve.

[The ships size offers enough hangar space for 60 planes according to SS rules. As the rules do not specify whether the planes carried are big or small, I assume hangar space allows the use of twin engine a/c.]

Is Peru also interested in buying shipborne a/c abroad or will home grown designs be used?

Japan can offer a new updated version of either the Chitose or the Soryu. IJN Carrier aircraft will be included in the package if Peru wishes for no additional cost.

The basic carrier orientation program for crew and pilots can start right away and will take place on carriers that are almost identical to the one(s) the Peruvians will be working on in the near future.

Hoo raises a point: Peru will be seeking the aircraft, too - both the operational air group and a reasonable number of replacements/parts.

The Dutch are willing to build a Walcheren class CV for the Peruvians with some updates (i.e. 1942 engines and the weight put into the armor deck). Since Peru does not need the range Dutch capital ships are build for, some of that bunkerage space could be partitioned for additional AVGAS.

The Dutch would be quite willing to accept Peruvian cadets on board the training carrier CV Hund in the Netherlands.

Gun battery includes 4 turrets fore/aft of the island. An additional 8 deck mounts are mounted at the corners of the flight deck, like the OTL Yorktowns.
The 23mm and 40mm mount alternate along the edge of the flight deck.

Aircraft capacity is 48 planes (2304 misc wieght)
SQRT (2304) = 48
LxB = 2200mx24.5m = 5390 /70 = 77

High freeboad is to represent an enclosed Hanger. This hanger option was one of several designs studied, and a smaller version of the vessel was submitted to Argentina for consideration.

It is anticipated the main armor belt extends 1m above the waterline to the armor deck, above which is a full 2.44m deck, and then the 5.5m hanger.

The 3.66m aft overhang represents the aft round-down, giving a 230m / 758 ft. flight deck. Three large centerline lifts are provided.

An extra 100 misc weight represents additional ventilation and fire fighting equipment.
40 tons is "Radar" /Fire control / Air control
50 tons is additional spares
80 tons misc is "spare" for domestic equipment.
26 tons is an unspecified.

Italy would like to offer the aircraft carrier Giovanni Caboto for sale. The vessel was laid down in the beginning of the 1930s as an aviation training ship and has seen good service in the Regia Marina throughout the past decade. However, at this current time, there are now enough aircraft carriers in the navy and a purpose-built training carrier is no longer required.

The current vessel meets the majority of the Peruvian requirements. Italy feels that the tactical impact of 30 or 32kts speed is small. The seaworthy nature of the ship ensures that higher speeds are maintained in heavy sea states. For protection, it appears that the Peruvian technical directorate is at odds with the Italians. Italy believes that achieving useful levels of protection would severely detract from effective aircraft operations. It is not practical to armour the whole of the ship against 152mm HE or SAP shells. Likewise, protection from 500kg or 1000kg bombs would add a very significant mass of armour high up in the vessel with consequent stability impact. Italy believes that the current mixture of splinter armour and the distribution of machinery on the unit principle to be the most effective means of protection. The ship is already fitted with the latest Italian fire-prevention and management devices, which are widely regarded to be amongst the best in the world - born out of costly experience with Francesco Morosini in the 1920s.

The vessel when designed put a lot of attention into future operation of aircraft types, with a designed aircraft mass of 10,000kg. Additionally a large single hangar was built into the design. Italy estimates that in full service, the vessel would operate 36-48 aircraft with ease (although there's a bunch more misc. weight and space, comparison with say Colossus/Majestic etc. seems that 48+ aircraft is unlikely for this size of aircraft carrier)

Italy would like to offer a number of options for consideration:

- 15% Refit : Additional of light anti-aircraft guns, likely quadruple 37mm mountings and 25mm singles. This would also include the installation of surface and air search radars and electronic landing aids.

- 25% Refit : In addition to the above, the extension of the flight deck to to port side a bit and incorporation of a small elevator. Some more powerful secondary armament in addition to the AAA could also be added. Italy would recommend a number of 76mm singles. Additional armour could also be added, but Italy feels that the current level of protection is sufficient for this size of vessel. Effective protection against guns, bombs or torpedoes would be challenging to incorporate and her ability to operate aircraft would suffer.

- 50% Refit : This would be a considerably more thorough refit and essentially result in an entirely new vessel. Bulges would be added to the vessel to maintain stability. Large areas of the flight deck would be extended and an additional large elevator mounted aft. A new, more powerful and more modern catapult would also be added in the bows. New boilers and turbines would also be fitted at this point rather than waiting for a possible re-boilering around 1950-55. It is believed that more modern units would be able to maintain or slightly improve the speed. (Additional misc. weight would also be added and this would likely result in a ~15,000t vessel. I haven't put this through SS yet)

For an airgroup, Italy would build on the Reggiane Falcos already in service with Peru. Accompanying the ship would be an airgroup of Caproni Ariete fighter-bombers (capable of carrying 1000kg bombs or torpedoes), although Peru may wish to purchase specific strike aircraft as well; in this case Italy would offer the sucessor to the Breda Ba.67 which is currently under development. Italy would also point Peru in the direction of Cierva in Iberia for a number of R1 autogyros that have proved useful in the reconnaissance and liason functions.

I thought the Falco was already in service and had been for some time... Maybe I'm just getting mistaken from previous conversations with Alvama, although you'll see them in his Almirante Aguirre drawings.

So maybe no commonality, but still a pretty good carrier fighter-bomber.

To the best of my knowledge (and with some quick research), the Peruvians bought Hurricanes (in 1935ish) and Defiants (1935ish), Boulton-Paul P.94s (1938ish), and then G.55s (1941ish). If Peru ever bought Falcos, then it was never posted - I tend to keep notes, for obvious reasons. I know that when Alvama and I were discussing carriers way back when, I suggested the Reggiane might be one of the more plausible choices to use in this period, due to the alliance connections and all.

Appreciate the input to date.

Questions:

-All in general: A sense of "slip charges" or "fees" for new-builds would be helpful.

-For those offering second-hand, a starting asking price would be helpful.

-For Russia: Was the Canopus being subject to a refit at the same time as her conversion? What is the date of the machinery? And what might the drydock rental fees work out ot be?

OOC : Hmm, never good at these. The Dutch let the Thais use unused slips in DEI 'at cost', but the Dutch-Thai relationship is stronger and more critical...still Peru is part of AEGIS....it would make Iberia happy... and we have 4 Class 3 slips going unused...nice to employ the dockworkers...still payment would likely be in installments, will need to arrange financing to allow materials to be ordered in advance, etc...say a 5% overage?

IC : A 5% fee is all that is requested.

As Peru is an 'F' Nation, the maximum charged is 5%, but it could be lowered (depending on Japan's mood and the position of the sun, the moon and the inner planets)
