Removing the 3.5-inch Mk8 semi armor-piercing warhead from the 3.25-inch Mk7 rocket motor..........using the RIGID 48-INCH PIPE WRENCH. This rocket-warhead combination was used for air-to-service engagement of tanks and submarines. The threads were concealed behind a collar and inaccessible for lubrication. WARHEAD & ROCKET MOTOR ARE INERT AND DO NOT CONTAIN ANY EXPLOSIVE MATERIAL.
ASROC... ALSO LOOK UP HEDGEHOG... THE GERMANS HAD THE FIRST REMOTE RADIO CONTROLLED ANTISHIP DRONES NEAR THE END OF WWII. THE GERMANS ALSO PRODUCED AND FIELDED THE FIRST "ASSAULT RIFLE", WITH A BOTTOM FED DETACHABLE MAGAZINE( CLIP). KALASHNIKOV COPIED IT'S DESIGN CREATING THE AK-47.
Me neither. Knew they had anti-submarine mortar weapons, like the Hedgehog and the Mousetrap. Maybe it's similar to those because they are technically rocket powered.
@@arthurneddysmithThey used the rocket propelled antisubmarine bombs as first stage atack, then continued by launching the depth charges using the aft inclined launchers, on probable submarine position, calculated by ASDIC data. Also, the rocket propelled bombs were used to breach the sea mine barrages, especially in harbour mouth areas or in narrow passage areas, where thorough MCM ops were not an option due to extensive time required.
This is what our company does. We specialize in the acquisition, restoration, and sale of inert ordnance, artillery, and related components. We have been buying inventory like this for 25 years. We sell all of our inventory on our website, which is Ordnance.com We are adding new items to the website 3 times a week.
We disassembled a 240mm mortar round once using a smaller pipe wrench…. and a really big sledgehammer, a wheel loader and absolutely no serious risk assessment
In the field of ammunition, AP by itself is usually a solid munition, the mass and strength of alloys does the damage and penetration SAP, Semi-Armour Piercing, is usually an explosive projectile with a Ballistic Cap added to the top of the warhead, this cap "shields" the warhead and allows it to first dig into the target and detonate once its been penetrated to deal more damage, the explosive does the damage, the ballistic cap helps it penetrate (not to mention the Fuse is usually behind the shell, to give better penetration coefficient) SAP warheads can also just explode if they fail to penetrate altogether, making them versatile against ships and vehicles or fortifications This is very simplified and not exactly correct, but I think everyone can understand And yes, SAP works vaguely like APHE, but not for the same reasons
@@CaptainGrief66Based on what I can find on this particular munition, it is solid steel with no explosive filler and was never issued and they instead went with a 5 inch version. So there might be some variation in SAP's meaning
@@MrDJAK777 A weapon of the sort having no explosive seems really weird, designations like AP or SAP are pretty standard, if it's SAP it should have some filler, otherwise it's just AP
@@CaptainGrief66 in the 1947 naval ordance (under navy rockets ) manual I'm looking at it states "3.5-inch Mk 8: The head is of solid steel and contains no high explosive or fuze. The round was developed to give better underwater travel, and replaces the 3.5-inch Head Mk 2." And describes the entire 3.5 inch rocket class as such " The 3.5-inch rockets were designed to be used again at smaller targets , such as submarines and tanks, for larger targets, the 5.0-inch rocket was developed from the 5-inch anti-aircraft shell" which gives me the impression (assuming these were 'sap') that at some point in time that SAP might just have meant for use against more "lightly armored" but still armored targets and or designed to cause internal spalling after impact for those same "lightly armored targets" Edit: all the same thanks from re/sparking my interest, fun stuff to look into.
A friend gave me a couple rocket heads he found in a firing range long ago. Might u know what they are. Their 2 3/4" They say MK 1 MOD 1 their about 11" long. They have been a mystery.
Learning a lot of new stuff with this one. First anti submarine rockets are a thing didn’t know that also pipe wrench’s can get that big. Seriously if the Halk became a plumber this is what he would use.
I think these rockets had a solid warhead. Exploding on the outer hull of a submarine wouldn't sink the submarine. However penetrating the outer hull and puncturing the pressure hull would disable a sub. If it forced the sub to surface it was a mission kill.
That's funny as hell that you noticed that. Gotta love 4k resolution. Yes, we bought about 50 or 60 at one time because they were put on clearance for something like .50cents/ea. Very handy for projects!
@bentos117 Ah, yes, water for cooling works, but certain oils and coolants are better. No need for any cooling though, as there is nothing energetic involved. Warhead is solid steel and the rocket motor is empty of propellant.
Always get a better bite in the front, versus the back. Been doing it the same way for 30 years, getting the intended result, without breaking tools, so not changing it up now 😂
If it were a live H.E. warhead and a rocket motor loaded with propellant, and had this much corrosion..........it would be a very bad idea to do what we were doing. BUT, solid steel warhead and empty motor, so no danger involved
