HISTORY
On April 25, 1942, the Regia Marina submarine Barbarigo left the La Pallice sub base in La Rochelle, France for a long-distance mission to the waters off the Brazilian coast. Barbarigo was under the command of Capitano di Corvetta Enzo Grossi. Previous missions under Grossi and the prior commanding officer, Capitano di Corvetta Giulio Ghiglieri, were relatively unfruitful with the sinking of a few merchant ships, with one belonging to neutral Spain. However, this sortie would lead to one of the stranger stories of World War II.
Barbarigo was a Marcello-class submarine, launched on June 12, 1938 at Cantieri Riuniti dell’Adriatico (CDRA) and commissioned on September 19th. She measured 239 ft 6 in (72 m) long, with a beam of 23 ft 7 in (7.2 m) and a draught of 16 ft 9 in (5.1 m). Barbarigo displaced 1,060 long tons surfaced and 1,313 long tons submerged. She was powered by two CRDA diesel engines and two CRDA electric motors generating a top speed of 17.4 knots surfaced and 8 knots submerged. Armament was comprised of eight 21-inch (533 mm) torpedo tubes, with four at the bow and four at the stern. Surface armament included two 4 inch/47 (100 mm) guns fitted forward and aft and pair of twin 13.2 mm (0.52 in) machine guns fitted on the sail.

Barbarigo reached Cape San Rocco of the Brazilian coast on May 17, 1942 and on the following day, attacked the Brazilian merchant ship Comandante Lyra with torpedoes and deck gun. C.C. Grossi was certain that the merchant ship was left sinking, but it was not. Comandante Lyra was ultimately towed to port by a Brazilian tugboat. However, during the attack the merchant ship’s crew managed to send an emergency signal which was picked up by U.S. Navy Task Force 23 operating nearby. T.F. 23 included the old cruisers Milwaukee and Omaha and destroyers Moffett and McDougal. On May 19th, lookouts on Barbarigo spotted an airplane launched by USS Omaha which failed to see the submarine. However, on the 20th, Barbarigo sighted the warships of T.F. 23 heading south to her location. Barbarigo moved into position and fired two torpedoes from her aft tubes at USS Milwaukee. C.C. Grossi and his crew were convinced that their target was hit and sunk and they later managed to evade the destroyers. C.C. Grossi informed BETASOM (the Regia Marina submarine base at Bordeaux) that he sank either a Maryland or California-class battleship, later confirming that it was a California-class battleship. Ironically, none of the American warships were even aware of the torpedo attack. While there was still some doubt as to the target, the news of the sinking of a U.S. battleship was reported home and was too good a bit of propaganda not to be widely publicized in Italian and German newspapers. Barbarigo returned to Bordeaux on June 16th and C.C. Grossi was hailed a hero. He was given a Gold Medal of Military Valour and promoted to Capitano di Fregata.

However, the tall tales of now C.F. Grossi did not end with this episode. On August 29, 1942, Barbarigo left for a new mission off the African coast. On the night of October 6th, the submarine encountered the Flower-Class corvette HMS Petunia. Apparently still on cloud 9 from his previous success and possibly with some grappa flowing, C.F. Grossi identified the 205 foot long, 925-ton corvette as a 382 foot long, 13,000-ton Mississippi-class battleship! Clearly C.F. Grossi did not know that both ships in this class were sold to the Greek navy in 1914 and sunk while in the port of Salamis by German aircraft on April 23, 1941. The submarine fired a total of 4 torpedoes at the “battleship” and all completely missed the corvette. However, C.F. Grossi and crew were once again convinced that they sank a battleship and reported this latest success to BETASOM. When the submarine returned to base on October 29th, C.F. Grossi was given another hero’s welcome, a promotion to Capitano di Vascello and a second Gold Medal of Military Valour. He was also reassigned as the new BETASOM commander.

Barbarigo conducted one final mission as an attack submarine in early 1943, with bona fide sinkings of three merchant ships and inflicting damage on another. Afterwards, Barbarigo was converted to a transport submarine, with decks guns removed, ammo magazines replaced with additional fuel storage and some crew accommodations converted to cargo space. These transport submarines were to be used to exchange commercial goods between Germany and its Axis ally Japan. She left Bordeaux on June 16, 1943 but disappeared enroute to Japan. Her loss remains a mystery, though British records indicate that an unidentified submarine was attack and presumed sunk between June 17th and 19th, in the area where Barbarigo might have been at that time.

While Barbarigo’s saga came to a close during the war, that of C.V. Grossi did not. Grossi’s actions were the subject of two enquiries, in 1949 and 1962. The 1949 enquiry concluded that Grossi and his crew, while wildly incorrect, had acted in good faith. However, Grossi was stripped of his promotions and gold medals. The 1962 enquiry upheld the conclusions of the 1949 enquiry. Enzo Grossi died in 1960 in Corato, Italy.

Thetis Models Barbarigo  
The Thetis Models Barbarigo kit is comprised of 3D printed parts, photoetch parts, turned brass barrels and rod and a comprehensive decal sheet. The contents come in a sturdy flip-top box with the color outer box top. The hull is wrapped in bubble wrap and the 3D printed part rafts, PE and brass items in plastic sleeves. The contents are snugly packed within a large sheet of bubble wrap.  
HULL 
The 3D printed full hull is very nicely done and sits on a large print raft with numerous attachment points. Most of the attachment points are rather thin expect for those along the keel with appear quite thick. Still removal of the hull should not be too difficult but I would expect some clean up, especially along the keel, will be needed. 

The hull is well detailed with chocks and bollards, strakes and torpedo tubes. The aft tubes are recessed and more pronounced while the bow tubes are represented by subtle recessed lines. The hull has deep recesses over which the photoetch deck sections will sit. This will allow for some of the photoetch hatches to be affixed in open positions. There is a recess along the hull to accommodate the photoetch bilge keels, but it is hard to see behind the raft print supports.

THE SAIL
The sail is printed on its own raft and it is also nicely detailed, with watertight doors, ladders, handrails and open bridge windows which can be glazed using Krystal Klear or are similar product.
Small 3D Printed Parts
The two next largest parts are the periscope tower and the bridge roof. The rest of the parts are printed on rafts that resemble sprues with the part numbers. One raft has the parts for the 4 inch/47 (100 mm) guns. The mounts are separate from the actual guns and you are given the option of either using the fully printed guns or just the breech if you use the brass barrels. This option is a very nice touch. The next raft provides the propeller struts, propellers, boat and anchor. The boat is actually fitted beneath the PE deck and corresponding hatch cover. If you wish to show off the boat, you can cut the hatch cover in half and pose it open to show the boat, otherwise it will not be visible. The last raft has two different types of deck hatch coamings.

PHOTO-ETCH
The kit has four different photoetch frets with corresponding part numbers etched into the frames. While the photoetch provides a large number of parts, after close examination of the kit instructions, it turns out that most of them are not used with this kit. Upon closer examination of the frets, three of the four have an earlier kit catalog number etched into them. That kit was an earlier release of a Marcello-class submarine that I believe is no longer in production.
The parts to be used on the largest fret include the helm, parts for the twin 13.2 mm (0.52 in) machine guns, various hatches, handwheels, seats and handwheels for the 4-inch/47 gun mounts, boat details, wire cutters, bilge keels and main deck railings, safety ropes and details for the periscope tower. Of the 53 parts on the largest fret, only 23 are to be used with this kit. The main deck railings have individual stanchions. Frankly I dislike railings like these as I find them a pain in the rear to attach to the deck. Luckily these are optional because according to the instructions, they were rarely used during wartime. With that excuse, I will omit them from my build.

The second fret has the main hull decks, which are nicely detailed with wood planking and other features. Only the deck sections are used, the remaining items are omitted.

The third fret is the only one designed specifically for the Barbarigo kit and it provides the decking for the sail, an antenna, rigging supports that are attached to the sail and sections of railing to be fitted around the sail on the main deck. Railing 92 appears not to have been fully etched, with some leftover bits of brass that needs to be carefully removed. The larger sections of railings, parts 86 and 87, have individual stanchions while the other railing sections have a bottom gutter rail. I have already stated my dislike for individual stanchions, but I guess fitting these in between the other railing sections may make it a little easier to attach and they do not have the option to be omitted like the main deck railings.

The fourth and final fret provides parts for a display stand, propellers, rudder and the forward and aft diving planes assemblies. A handful of parts on this fret are not used.

BRASS PARTS
A pair of turned brass barrels for the 4-inch/47 guns, with muzzle openings, are provided. A section of brass rod is also included. The rod has to be cut into smaller sections as per the assembly instructions.
DECALS 
A single decal sheet is included which provides flags, ensigns, pennants, draft markings, ship name in two sizes as well as kill markings. Not all of the decals are used together and the instructions provide guidance on the proper and accurate use.
INSTRUCTIONS
The assembly instructions come in a 12-page booklet with text in both Italian and English. The first 3 pages have the history and technical data for Barbarigo, first in Italian and followed with an English translation. Page 4 has a breakdown of the kit parts and images of the photoetch frets and decal sheet. Oddly, the image of the photoetch designed for the kit and the decal sheet are blacked out. Page 4 also has the templates to cut down the brass rod provided with the kit. Page 5 has assembly notes, symbol explanations and requisite cautions in both languages. Pages 6 through 10 have nicely detailed assembly diagrams with bilingual annotations as needed. Page 11 has instructions on decal placement with notes on which ones to use at certain points in Barbarigo’s career. This page also has a rigging diagram for the radio aerial cables. The final page has painting instructions with some of the colors having FS references. 

 
FINAL THOUGHTS
Overall, I find this to be a rather complete kit that should build into a detailed model of a submarine with an unusual history. Due to the amount of photoetch to be used and the complexity of some of the assembly steps, I would recommend this kit for modelers with moderate to advanced experience. This kit is available directly from Thetis Models (www.thetismodels.com) and is priced at €55.00 (or about $60.00 US). I was able to purchase this kit at a pre-order price of €49.50 (about $54.00 US) plus shipping. Thetis Models specializes in Regia Marina subjects and I am looking forward to what other kits they will produce.
