The control fins which @porky_kicker posted are not for booster or surface control of the missile atleast. These are for RV control and no it is not the first that we have such fins on a missile.

I still stay corrected till now @porky_kicker

I will send u something on the no , within a month or so

Keep 2 takeli lau Pani , gahori and hah ready :biggrin2:

For me :biggrin2:

Off route mine

DRDO is developing one. It uses EFP warhead and acoustic and seismic sensors to acquire target and trigger the warhead

What exactly is an off-route mine?

 

[porky_kicker]

What exactly is an off-route mine?

Simply speaking off route mines are those mines which are placed at a distance away from where the target is likely to pass.

Most mines r placed underground directly beneath the expected target , off route mines are generally overground but not necessarily and importantly acts from a considerable distance whenever it detects a target within its zone of influence.

Consider it to be a standoff mine

So if they explode in a distance, won't the effect be less?

Are these anti-infantry fragmentation mines?

Look at that copper shaped charge. It would let you know what it is.
@porky_kicker already spoiled the game.

These are anti-armour.

My old no is not working. DMing you the new number.

Looks like the anti helicopter efp mine Russia showed off couple years ago

 

[Bleh]

Normal anti tank mines would blow the tracks with sheer power of the explosion. So how exactly do these things work from a distance on on steel vehicles?...

...or helicopters up in the air?!

These are mostly used for anti-vehicle mines. The concave copper disk gets shaped into a long slug by the explosive shockwaves

https://en.wikipedia.org/wiki/Explosively_formed_penetrator

Quite difficult to deal with, think of it like a AP shot travelling at 2000+ mps, far faster than if fired from a gun.

Thanks for explaining... but although these things faster this is just a deformed plate. It will rip through light-armoured or soft-skinned vehicles, but will it be able to damage thick & hard steel tanks etc. or get squashed instead?

Thing is, at these kinds of velocities, the hardness of the materials don't matter. Even hardened RHA steel has different properties when meeting a hypervelocity object. Overall think of it like the pressure created at the contact point of the slug and armor steel exceeds its yield strength.

But it's true that the diameter of the copper liner matters. A small roadside efp mine which takes out a humvee won't be able to disable a mbt. A large enough efp mine would be eventually be able to disable a mbt class target, but at that point it might be too large to conceal or too cumbersome. A better trick is to fire the slug from top, where the armor in thinner.

Bill 2 ATGM with overfly-top-attack warhead.
TOW 2B heavy ATGM
BLU-108 air-delivered sub-munition, another example is CBU-97
155 Arty delivered SADARM

Technically EFPs are a subset of the shaped charge or HEAT mechanism. Same copper plate will form a jet of metal instead of a solid slug if it's made more conical on the concave side.

I mentioned EFP

EFP - explosively formed penetrator

Old pic of DRDO experimenting with EFP for off route mine

The pic shown in the Twitter post is not the Indian ( DRDO ) system

 

[porky_kicker]

DRDO work on smart Munitions to defeat enemy armour from its vulnerable top.

Explosively Formed Projectile (EFP), a copper liner serving as antenna for the sensor in the search mode and forming a single projectile in the attack mode. Detonator Arming Safety Device for activating EFP warhead. Capsule ejection system. Highly compact MMW sensor. Rotatoil parachute for stabilising the sub-munition and scanning the ground for targets.

Similar smart munitions are being developed for mortars , artillery shells , aerial bombs , warheads of rockets and missiles and finally drones.

CBU 105 rings a bell ? Same type

MMW probably is good for function independent of ambient temperature. None of that hot desert sensor failure.

@Rassil Krishnan This is the garbage truck u were talking of.

The garbage truck in detail :biggrin2:
