First launched in 1991, the SHINKAI 6500 is a manned submersible that can dive to depths of 6,500 meters (20,000 feet). Operated by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC), Shinkai has completed over 1300 deep dives in the Pacific, Indian and Atlantic oceans, as well as the Sea of Japan.

In 2012, the vessel underwent a major upgrade, including conversion from a single aft prop to two thrusters and the addition of one more horizontal thruster for maneuverability. Hasegawa offers the kit with two build options to reflect the original and upgraded version of the submersible. To clarify the build process and the differences, the instruction sheet includes complete build sequences for each version. It's worth taking the time to go through the instructions – particularly since other sub-options are offered within each build – to end up with the configuration you've chosen.

Osprey Publishing’s latest edition in their Raid series looks at sinking of the HMS Royal Oak by German U-boat U-47 in 1939. From the website: "At the outset of World War II, Scapa Flow was supposed to be the safe home base of the British Navy - nothing could penetrate the defences of this bastion. So how, in the dead of night, was Gunther Prien's U-47 able to slip through the line of protective warships to sink the mighty Royal Oak? This book provides the answer with an account of one of the most daring naval raids in history. Drawing on the latest underwater archaeological research, this study explains how Prien and his crew navigated the North Sea and Kirk Sound to land a devastating blow to the British."

From the very beginning of the Second World War, Great Britain was aided in her naval war against the Axis Powers by officers and sailors of her former colonies, or Dominions, as they were formally known. In this Osprey New Vanguard edition, naval historian Angus Konstam begins by describing the somewhat complicated arrangement of how Britain’s former possessions were differentiated as colonies, protectorates and Dominions. Dominions, known as Commonwealth Nations after 1926, were described as “autonomous communities within the British Empire”, and were to varying degrees, responsible for their own defense, yet were expected to contribute to the overall defense of the empire as a whole.

Dragon continues to expand its “Modern Sea Power” Series, this time with the introduction of the 1/350 Zerstorer Class 1936A, with a twin 150 mm turrets.

Upon opening the box you find 18 sprues, plus two small photoetch frets and decals. There is a total of over 550 parts on this kit.

The parts are finely molded, with virtually no flash anywhere. I’ve only was able to spot a bit of flash in one sprue, around the propellers. Slide mold technology was used extensively in the kit minimizing seams and allowing multiple pieces (bridge, hull) to be molded in a single piece. It should be noted it the hull is packed with a small protector to protect the sharp bow from being damaged.

The Japanese Agano-class of light cruisers had a total of 4 ships on its class: Agano, Noshiro, Yahagi and Sakaw. These ships were lightly armored command vessels that operated for destroyer and submarine squadrons.

Hasegawa has released a detail set for its Agano Class in 1/350. This set includes

• Type-41 twin 15 cm guns (x2)
• Type-41 twin 15 cm guns with rangefinder (x2)
• Type-98 twin 8cm hi-angle turret

The Agano class boxing includes the standard Type-41 and Type-98, what is added is the rangefinder and some details parts for the standard turrets to model the Yahagi and Sakawa.

The overall surface detail is excellent –as you expect from Hasegawa- and the molds are completely free of flash. The cannon holes need to be drilled, but that is to be expected of plastic parts.

This detail set is a welcome addition as it allows the base Agano kit to be converted to other ships of the same class.
