Splash colors/Dye Capped rounds and SanKaidan (Giga dragons breath round for module disabling)


Recommended Posts

People can and will argue about anything and everything, can jet fuel melt steel, did the use phosphorus to destroy Geman guns.  What we can agree about is melting steel glued to steel is hard to get out of the way or use for anything but a paper weight.   Sankaiden was designed as a aa round for battleship cannons, was it more a light show like dragons breath shotgun shells who knows.
 My idea is to create a anti-module round for modules with light armor, secondaries - AA guns - torpedoes and radar arrays.  Use to shoot down that is battleshops clapping cruisers and cruisers clapping destroyers and finnaly everyone clapping fighters.  I like the ide of tempporary and permanentaly disabling modules as much as a strategy as punching through ships citadels, burning down ships or filling them with water.  
My second idea is splash shells, no now shell that splashes water all my shells seem to be doing that job even when a should be hitting the enemy.  Splash sshells were filled with dies so you could tell you're shells from those of you're squad mates.  I know sparays but we got posters in enlisted, it could be fun, ok something for the people who whiff so many shots like me, hell splashing dye or paint over the hull of a ship could make a fun even (world o warpant).  We already have commander guises that give shells colored trails a they fly through the air.  Imagine the sea a rainbow of colors could be fun would also be something to add to new guises or ship skins.

Splash Colors - In group actions, when more than one ship is firing on the same target, it is difficult to determine which shell splashes are from which ship. This is important to know in order for each ship to be able to accurately adjust its fire onto the target. The solution was "Splash Colors," first used by the USN during Force Battle Practice in 1930 and in use by most navies during World War II. The void space between the armor piercing cap and the windshield for AP projectiles was filled with a colored dye by the shell manufacturer. The dye is seen when the shell impacts in the sea and colors the resulting splash - hence the name. By using different colors, each ship could distinguish between their shells and those fired by other warships. In the USN, the dye was a dry powder which was packaged in paper bags. Interestingly, the USN used this dye to compensate for minor weight variations that crept in during the projectile manufacturing process. For example, the 16 inch (40.64 cm) Mark 8 AP had a nominal 1.5 lbs. (0.68 kg) dye bag, but this was allowed to be as large as 3.0 lbs. (1.36 kg) in order to bring underweight projectiles up to the standard weight of 2,700 lbs. (1,225 kg). Usually, a particular color was assigned to each ship. For example, the colors used by the USS Iowa (BB-61) class battleships were as follows:

  USS Iowa - Orange
      USS New Jersey - Blue
      USS Missouri - Red
      USS Wisconsin - Green

Dye capped shells used by French & British Navies

The ballistic cap within the French 380mm main armament shell, housed a dye bag which served to colour the shell splashes in order to facillitate spotting when operating in company with other ships; a small burster and nose fuse ensured dispersion. The Jean Bart was assigned Orange dye, whilst the Richelieu contained Yellow.

Now this technology which was known as Dispositif K was offered to the British in 1939 as part of a two-way transfer which on the British side included Asdic. Subsequently adopted by the British for their own heavy shells.

Does anyone have any further info on the technology but more importantly on what dye colours were assigned to British Capital ships and any other French/Allied Capital ships. Also was it used by the USN?


Shrapnel - Also known as "spherical case," this was a type of anti-personnel ammunition which consisted of a shell containing metal balls in the front and a small bursting charge at the base which was detonated by a time fuze set to explode just before reaching the target. This was first adopted by the British Army in 1803 and is named after the inventor, Lt. (later General) Henry Scrapnel (sometimes spelled as "Shrapnel") of the British Army. This term has been used in the past to define shell fragments from most kinds of bursting projectiles, not necessarily anti-personnel types. Currently, the more accurate term "shell splinter" is in general use.

During World War II it was found that a high-explosive bursting charge fragmented the shell's iron casing so effectively that the use of shrapnel balls was unnecessary, and it thus was discontinued. The term shrapnel continued to be used to designate the shell-casing fragments.Sep 16, 2023

Shrapnel | Explosive Shells, Fragments & Projectiles - Britannica



Sankaidan - Japanese for "fragmentation." Also known as "incendiary shrapnel shells" (shôi ryûsandan). These were AA rounds which contained hundreds of incendiary-filled steel tubes and officially designated as "Type 3 Common Shells" (3 Shiki tsûjôdan). The incendiary filling was "Elektron" metal (45%), barium nitrate (40%) and rubber (14.3%) together with sulfur (0.5%) and stearic acid (0.2%). "Elektron" was a trade name for a metal alloy composed primarily of magnesium (90%) with the balance being aluminum (3%), copper (3%), zinc (2%) and silicon (2%). Besides their incendiary effect, the steel tubes also acted as shrapnel. The Type 3 was first deployed in 1942 for 20 cm (8 in) and larger guns and in 1943 for the 12.7 cm/40 (5 in) AA and 12.7 cm/50 (5 in) DP guns. The 46 cm (18.1 in) Type 3 projectiles for the Yamato class battleships may have been nicknamed "The Beehive" but this could be apocryphal. A time fuze was used to set the desired bursting distance, usually about 1,000 meters (1,100 yards) after leaving the muzzle. These projectiles were designed to burst in a 20 degree cone extending towards the oncoming aircraft with the projectile shell itself being destroyed by a bursting charge to increase the quantity of steel splinters. The incendiary tubes ignited about half a second later and burned for five seconds at 3,000 degrees C, producing a flame about 5 meters (16 feet) long. These shells were thought to have a larger lethal radius than did standard HE AA rounds. The concept behind these shells was that the ship would put up a barrage pattern through which an attacking aircraft would have to fly. However, the USN pilots considered them to be little more than fireworks and not an effective AA weapon.



Dragon's breath is a special type of incendiary-effect round for shotguns. Dragon's breath consists primarily of magnesium pellets/shards. When the round is fired, sparks and flames can shoot out to about 100 feet (30 meters), although, some sources claim it extends to 300 feet (91 meters).[1] Dragon's breath is normally chambered in 12-gauge 2+3⁄4″ (18.5 mm × 69.9 mm) shot shells. The rounds are safe to fire out of an improved cylinder bore as well as a modified choke barrel, common on many shotguns.[2]


They used airburst rounds in that engagement as well. The shrapnel cut down men that were out in open AA mounts but left the main guns and vitals very much intact. An after action report thought they were some sort of pyrotechnic shell that was meant to either blind or confuse gun crews.Sep 12, 2017
Are HE shells actually used in real life naval engagements?===================
