Before and After Challenge

[Kiwi Imperialist]

Welcome everyone to the Before and After Challenge where participants are asked to draw a vessel before and after a substantial reconstruction which meaningfully alters its role. Please do read the design requirements and challenge rules outlined below and follow them as best you can. Remember, for this challenge, you will need two drawings: one showing the vessel before its reconstruction and another after. If you have any questions, feel free to ask. If you have an idea for a future challenge, remember to share it in the Future Challenge Ideas/Suggestions thread. Don't be afraid to share an idea which has been suggested by someone else. It shows that multiple people are interested in that topic.

Design Requirements

1. Your submission must depict a ship, submarine, or other watercraft before and after a substantial reconstruction or refit.
2. The reconstruction or refit should meaningfully alter the role of the watercraft (e.g. converting the Baltimore class into guided missile cruisers, rebuilding the Ise class into aviation battleships, or transforming Jupiter into Langley).
3. The 'after' configuration must be fictional, but you may use a real design for the 'before'.
4. The 'before' configuration must have been laid down, but does not need to have been completed or have entered service.

Challenge Rules

1. Each participant must submit two images, one depicting the vessel before reconstruction or refit and the other after.
2. Each image should be a Shipbucket template modified to include the participant’s art and, optionally, one of the following: vessel badge, unit insignia, manufacturer logo, national flag, or naval ensign. Other elements, including data sheets and scenic elements, are not permitted. If you have specifications and blocks of text, please include them as text in your post and not in the image itself.
3. In each image, one side-view of the participant's vessel must be included. One top-view is also permitted, but not required. All other views are prohibited.
4. If two views are included, they must depict the same individual vessel in the same paint scheme, markings, and configuration.
5. All art must be in Shipbucket scale and conform to the Shipbucket style guidelines.
6. A textual description accompanying each submission is permitted, but not necessary.
7. Non-serious entries, or entries substantially deviate from the challenge requirements, are not allowed.
8. Off-topic posts will be reported to the relevant authorities.

This challenge will run until Sunday the 2nd of February, ending at 23:59 UTC-12 (International Date Line West).
A countdown timer can be found at this link.

A poll will be held after this date to select a winner. When it opens, please provide honest and meaningful scores for each entry. Responses which grant maximum scores to a select group of entries, and minimum scores to all other entries, will be deleted. Members of the community who manipulate the results in such a fashion may also be subject to a permanent ban. Scores will be allocated in two categories, each with a scale of 1 to 10:

• Drawing Quality - The overall quality of the drawing. One might consider detailing, shading, and accuracy.
• Design Quality -The quality of the design presented, irrespective of drawing quality. One could consider feasibility, practicality, and realism.

Changes to Before and After Challenge Requirements
The following 'requirement' has been added to the Before and After Challenge: "The 'before' configuration must have been laid down, but does not need to have been completed or have entered service." This means you can draw ships like those of the Lexington-class, which were laid down but never completed as battlecruisers before their conversion to aircraft carriers.

My entry, mostly for the LOLz and purely because I can, and have, is a conversion of the battleship Vanguard into a late-war aircraft carrier. I've used her 1941 design/hull as a base, and as such does not have the sharper bow rake, and her propellers are spaced closer together (lesson learned from the sinking of the Prince of Wales.)

Turning this:


Into this:


She has a grand total of 16x4,5" guns in twin dual-purpose mounts, 60x40mm Bofors guns in 10 sixtouple mounts and 40x20mm in twin Boffin mounts.
Her airgroup consists of 30xF4U Corsair fighers, 14x Fairey Firefly figher-bombers and 26x TBF Avenger torpedo/high-level bombers.
Since she's a conversion of an elready existing hull, she only has one large hangar, as opposed to the usual British two smaller hangars. This is why she can have Corsairs instead of Seafires. The larger hangar also allows suspeding spare planes from the ceiling and the practice of deck parking (as per British Pacific Fleet, and not Mediterranean and Atlantic fleets) allows the somewhat inefficient carrier design to carry about as many planes as any other British fleet carrier.

Greetings!

Before: Lewatobi Class battleship:


After: Havik Class aircraft carrier:

Two Lewatobi class battleships cancelled under the Washington Naval Treaty were converted to aircraft carriers; KNS Havik (ex-Masurai) and KNS Valk (ex-Ranau). They retained the machinery of their battleship cousins but with a much reduced armor scheme. They were armed with 8 x 190mm (4 x 2) and 16 x 102mm guns when built and could carry 60 aircraft (72 w/deck parks).

Cheers!

HMS Lightning 1598 (OTL 1948) - Lightning 1611 (OTL 1961)

The L-class were Irvennia's last gun cruisers, ending a lineage that started with the A-class a quarter of a century earlier. Originally ordered as K-class cruisers, the ships were cancelled and reordered to a more radical design following successful trials of a new automatic 6" dual-purpose gun. They entered service after the end of the Great Global War they were originally designed to fight in, with only two ships being commissioned before the rest of the class was cancelled.

However, a tense Cold War ensued, and the rapid advance of aicraft and anti-aircraft technology gave the L-class a new lease of life. Despite political and financial upheaval, Irvennia was under pressure to bolster the naval defense capabilities of its new continental allies in case the war with Cebergaard reignited.

Irvennia had been developing a large, guided, surface to air missile under a secret project codenamed "crossbow". The size of the L-class identified them as suitable candidates to carry the heavy launcher and fire control installations. Despite being relatively new ships, it was judged that their all-gun arrangement would quickly limit their value. As such, the rear armament was replaced with the distinctive lattice missile launchers, and the superstructure was completely rebuilt to vastly improve command and fire control facilities. The forward guns were retained as backup and for shore bombardment duties, as well as limiting the balooning cost of the project.

The ships would serve for another quarter century, with their large hull accepting further upgrades and modifications before their eventual retirement and scrapping.

HM Pansarskepp Fädernslandet

Designed as part of a new naval procurement program for the Royal Swedish Navy, the Fädernslandet-class was a series of 3 5 masted ironclad frigates consisting of the Fädernslandet, Trossö and Gotland. Sensing a growing insufficiency in the navy's capability compared to new developments in the navies of Europe, the Fädernslandet-class was designed to be the most heavily armed and armoured ships in the Baltic Sea.

Armament:

4x 9 inch muzzleloaders
22x 8 inch muzzleloaders
2x 7 inch muzzleloaders



RI Catania

Despite only being a few years old, Fädernslandet was approved for sale to the newly established Italian Regia Marina to bolster their capabilities in the Mediterranean to replace the Re d'Italia that was lost during the Battle of Lissa in 1866. The ship was renamed Catania and assigned to the Primary Armoured Squadron (Squadrone Corazzato Primario) as its flagship, being used mainly as a deterrent to the Austro-Hungarian Navy throughout the 1870s-1880s. In 1890, the ship was chosen for a drastic refit that would see her rigging removed and the ship rebuilt as an armoured cruiser. Her ironclad armour was replaced with modern "sandwich" armour that greatly improved her survivability and she was rearmed with 12 modern 6" deck guns while still retaining her broadside 8" and 9" cannons (albeit with new ammunition). In the early 1900s, she was given a new mast for usage as a mooring point for airships and assisted with various airship expeditions around the world. The ship would go on to serve in WWI, assisting with the Capture of Toulon in 1916 by shelling key points ahead of the Regia Esercito's assault force. Catania would be delegated to training duty after the war and be the first maritime casualty of the Regia Marina when she was sunk by French saboteur frogmen in 1943.

A very big THANK YOU is due to Mr. Jetman for the lore for this, as a part of the AU we are working on together!

In 1861, the Peravlizan passenger steamer Rio Valdo was launched at the William Rogers Shipyard in São Maldoro, Peravliza, along the Mozilo River. Named for a small branch off of the greater Mozilo river, she was launched as a standard sidewheel river steamer for the Silves Transportation Company, which was a major driving force in the nation’s movement into the industrial age. Her career as a passenger steamer would be largely uneventful, mainly being used as a ferry on the eastbound service from the capital São Maldoro to the coastal port of Rio Leste. In January of 1865, Peravliza would be plunged into war as anti parliamentary rebels who sought to bring down the corrupt then Prime Minister, Francisco do Amaral.

During this war, heavy fighting would occur along the Mozilo River between Peravlizan and rebel forces. In order to turn the tides of battle, the Peravlizan Navy requisitioned paddle boats and screw steamers alike and retrofitted them with light armament to combat the rebel threat, the rebels doing the same to similar though often smaller types of ships. However, as the war progressed into the opening weeks, entrenched riverside gun batteries would soon become the most effective tool rebel forces had to combat Peravlizan vessels, inflicting heavy losses upon the lightly protected ships.

On February 18th, 1864, a parliamentary order was sent out to the Silves Transportation Company to donate three large paddle steamers to be converted to Ironclads back at the William Rogers Shipyard in São Maldoro. At the time, Peravliza had only 2 Ironclads, the NMP São Maldoro, and the NMP Almirante Augusto Pinheiro. Both ships were built by contractors in the Grand Syrennic Duchy as broadside oceangoing ironclads. Both ships had too great a draft to sail up the smaller branches of the Mozilo river.
The Rio Valdo was selected the following day along with the Rio Caipuru and Rio Flechal to be converted. It would take till December of 1864 for the first ship, Rio Flechal to be launched under the new name NMP Rio Leste. During launch, the NMP Rio Leste would sink deeper than expected and shortly thereafter sink. The sinking was attributed to the improper building techniques used by local designers, as the original William Rogers Shipyard designers refused to assist in designing a warship due to pressure from the Syrennic government. NMP Rio Leste would be resurfaced and redesigned, however not before Rio Valdo, now NMP Paranápolis could be launched on the 20th of March, 1865. NMP Paranápolis would also sit lower in the water than expected, however not low enough to be considered a problem. During her gunnery trials in early April, NMP Paranápolis would sit even lower due to the weight of her coal and armament, earning her the nickname “O Pato Gordo”.

Her first actual engagement would take place on the 28th of April, 1865, where she was used in tandem with three gunboats to sail up the Acarai River and help the 23rd Infantry Regiment of the Peravlizan Army take the town of Mocambo. During the engagement, the NMP Paranápolis and the three escorting gunboats would take so many hits that one of the gunboats would be forced to turn back after losing their armament. Paranápolis would continue to fire until the small impromptu fort at Mocambo was finally overrun and taken by Peravlizan army forces. During the Battle of Mocambo, The NMP Paranápolis would be given a completely different nickname by rebel forces “O Inquebrável”, due to how many direct hits she took with next to no damage after the battle.
NMP Paranápolis would serve until the 3rd of May 1866, when she was finally sunk by a mine during the Battle of Aguiar. Her legacy was honored in 1994 with the commissioning of the NMP Inquebrável, a helicopter carrier built in Syreland that would bear the nickname given to the Paranápolis during her famed battle at Mocambo.

Carrión-class Anti-Aircraft cruiser (April, 1941)




BAP García & García cruiser after its modernization at the Coquepala shipyard (now in French Polynesia) in 1941.


After the events of the Second Sino-Japanese War (1937), the Battle of the Rio de la Plata (1939) and the defeat of France (1940) at the hands of the Axis forces, the superiority of the Italo-German forces in air-naval matters with respect to the armed forces of the South was demonstrated, An emergency plan was initiated to modernize the armed forces, especially the naval forces, in an attempt to guarantee the security of navigation between the metropolis and its insular states against the fleets of submarines, corsairs and air raids, mainly against the Japanese Empire.

Among these plans was the modernization of 12 of the 14 Carrion class cruisers to become air defense and convoy escort units, as well as secondarily anti-submarine combat, leaving surface combat rather limited due to their light armament.

The unit represented is the third of the class (CL-13), commissioned by 1925, originally serving as escort and destroyer flotilla leader, participating in regional conflicts in the 3rd fleet, and being transferred to the 5th fleet by the end of 1936, where it would participate modernized in the second world war as part of the ABDACOM (In this universe, it would be the ABDAPCOM), being sunk during the Battle of the Java Sea (1942) due to multiple hits of maximum caliber of the IJN Nachi, as well as 2 consecutive torpedoes of destroyers.

Her insignia would be recovered much later and placed in the Callao Naval Museum (1985), where it is exhibited to this day.
