Cod Class

An ACM class, of which two were retained in GC service.  One unit was lost in action against French forces; the other remains active.

The primary difference from the original design is the armament, the 6" guns being exchanged for eight 14 cm guns, two of them replacing small 3" guns on the beam; the other 3" guns have been swapped out for 6.5 cm guns. Since the ships came along with a useful load of torpedos larger than the type employed by Gran Colombia, the original torpedo armament was retained. Some reduction in total miscellaneous weight was necessary to facilitate this.

Puerta Espana Class

This is not necessarily the best thought-out design Gran Colombia's put out.  Speed, armor, and range are all "okay" but the design as a whole is not really optimized either for trade protection or anti-destroyer ops.  It'll be a learning experience.

Westmoreland Class

The Westmoreland class belted cruiser is an improvement on the Puerta Espana II design laid down in 1905.  Superficially, the design has one less main gun, and two additional quick-firing weapons.  On the other hand, the armor protection is improved and, more importantly, the ship is five knots faster, courtesy of a major step forward in GC turbine design (which is to say, getting to engine year 1909).

The class is expected to work with the Armada's armored cruisers, using their speed to shadow and harass heavier units or their armament and armor to prevent torpedo attacks against the armored cruisers.

The name of the lead unit, and probably one other, will come from Jamaican parishes; other units will be named for administrative districts in the Heartland.

Galapagos Class

Galapagos and Trinidad are near-sisters to the Westmoreland class laid down earlier in 1907.  These have been configured to be capable of minelaying, carrying one hundred mines in splinter-proofed compartments aft of the last funnel.  The mines are rolled off rails on either side of the aft 140 mm gun.

To do this, the ships have reduced deck armor and slightly less powerful machinery.  The top speed is still respectable at almost twenty-seven knots.

Boyaca Class

The Boyaca class is intended to fulfill trade protection, minelaying, strike, and colonial station command functions in one tidy, speedy, economic package.  It is expected that one will be built and deployed to each of the distant regions of Colombian Polynesia and Coquimbo.

Grenada Class

The Grenada class protected cruisers are an enlarged version of the Westmoreland class ships.  The class features 50/50 oil-sprayed coal-firing and oil-burning boilers, with sufficient range to operate with the battlecruiser Luchador once completed.

The increased size of the ship happens to allow for an additional 140mm gun forward, and two 65mm anti-airship guns are installed aft.

Two units are planned for 1910.

San Lucia Class

Exercises by the Battle Fleet have demonstrated that maintaining its coherency can be difficult in conditions of poor visibility (gun smoke, coal smoke, night, rain) and battle damage.  It was decided that a pair of cruisers, derived from the earlier Boyaca class, should be built to assist CinC Battle Fleet in exerting proper control over his force.

The ships are superficially almost identical to the Boyacas, but there are differences internally.  The bunkerage is mixed, and the armor scheme improved; minelaying equipment has been eliminated.  Instead, the ship features additional command and communications facilities, including working space for a flag officer and his staff.

In action, it is likely that one of the class would be functioning as flagship of the screening force of cruisers and torpedo-boats.  The other would either be operating with the scouting elements or pacing the battleline on its disengaged side, relaying signals and, if necessary, functioning as an alternate flagship if the primary flagship is disabled.

Saint Thomas Class



The Saint Thomas class protected cruisers (yes, the first one is a Jamaican unit) are designed to operate as screening units for the armored cruisers Warrior and Matador.  They are larger and faster than previous Gran Colombian protected cruisers, but follow the same general design philosophy.

The main battery remains in single mounts, as Gran Colombia is not yet satisfied that an eight or ten gun ship with twin mounts is any better than a small armored cruiser with turreted 194mm guns.  Seven singles offers a decent broadside, even if forward and aft fire is more limited.

The Gran Colombian program to research Fire Control is well along, but running into some difficulties that delay it; the class is designed to include fire control directors, it's just a question of how far along the ships will be when the guys in the white coats finally figure out what they're doing.

Guyana Class

Following some unsuccessful trials in airship/warship docking, the Armada has authorized construction of a single "zeppelin cruiser" for further trials.  She has been named for the state of Guyana, where the Republic's airship program was first developed.

The ship is, in theory, a forward operating base for airships that might be operating in scouting roles with the Armada.  Being able to fuel them, rotate out the crews, and fix a few minor problems should enable the airship(s) to remain in the vicinity of the fleet for a full day or more, rather than having to head back to the nearest coastal hanger.

The ship has a complement of thirty deck crew and berthing for six extra airshipmen, all of whom are counting within the ship's normal berthing requirements due to the undergunned nature of the vessel.

The ship is based on a Boyaca class cruiser, with a fuller stern and correspondingly higher block co-efficient.  The ship retains many cruiser characteristics, including battery, armor, and speed.  This is primarily for the sake of her own survival, since she's not suited to surface combat.  

If it works, it may inform future GC carrier doctrine.  If it doesn't, she may wind up converted to some other function in a couple of years.
