QUOTE(thpace @ Jan 9 2016, 11:26 PM) Not necessary HE round must be that shape HE is different from HEAT. HE is solid-packed while HEAT is hollow charge.

QUOTE(thpace @ Jan 9 2016, 11:42 PM) Bizarrely, this looks like an anti-tank gun shell designed to be fired from a rifled gun (note no stabilizing fins). If this shell is indeed a HEAT round then it will be a poor one indeed. For full effect of HEAT penetration to take place, the round can't be used with a rifled gun. The spinning movement of the shell rifling will deform the plasma jet created when the warhead detonates and the plasma cannot concentrate its jet stream to punch into armor effectively . That's why you always see HEAT rounds with stabilizing fins, so they don't need the spinning movement of the rifling to generate accuracy.QUOTE From Wikipedia: HEAT warheads are less effective if spinning, and grow ever less effective with faster spin. This became a challenge for weapon designers: for a long time, spinning a shell was the most standard method to obtain good accuracy, as with any rifled gun. However, the centrifugal force of a spinning shell disperses the charge jet. Thus, most hollow charge projectiles are fin-stabilized and not spin-stabilized.[7] Such rounds could be fired from smoothbore barrels, losing some accuracy.

QUOTE(KLboy92 @ Jan 10 2016, 12:11 AM) French ran into problems with EC725 in desert, cannot operate in temp >40 degrees, sand filter ineffective, high engine maintenance compared to NH90. Tat issue is minor for a heli. Both nh90 and ec725 was never designed to be desert operated. Nh90 also got issue in desert deployment as noted For deploymen purposet.. well a ramp is always better. Do note that the nh90 was close to be chosen if not for some last minute changes for non ramp heli to participate for our cssr requirements |

Why not, british know riffled reduce range but still go for it |

A big change is coming to the Marine Corps ![]() QUOTE Navy official told the Marine Times that only titles where the word “man” appears as a separate word will be changed. Therefore, titles like “infantryman” and “rifleman” will go unchanged. Whereas, “reconnaissance man” or “field artillery sensor support man” will simply have the word “man” removed. http://www.businessinsider.my/a-major-chan...CPO8jbsUrreP.97 |

Do note that the nh90 was close to be chosen if not for some last minute changes for non ramp heli to participate for our cssr requirements NH90 no issue now in desert operation, NH90 use alot in Afghanistan and mali as CSAR。 QUOTE(KLboy92 @ Jan 10 2016, 12:50 AM) eh I dunno just what I've read online.

Nh90 design is for Navy and best helicopter for navy due to balancing in term size, space & technology。 later Army version as transportation/SCAR helicopter. Nh90 have very long range fly so not really need refuel. it can fly 900km with 2.5 tons load. 1600km ferry range with external fuel tank. Special Ops use EC725 more suitable, it design more to Air-force and Ops team use. This post has been edited by waja2000: Jan 10 2016, 01:49 AM |

Indeed, EC725 was for spec ops use but due to aforementioned problems French spec ops switching back to NH90... except EC725 has aerial refuel capability so Frenchies kinda NH90 no issue now in desert operation, NH90 use alot in Afghanistan and mali as CSAR。 Nh90 design is for Navy and best helicopter for navy due to balancing in term size, space & technology。 later Army version as transportation/SCAR helicopter.

So now French mainly use EC725 for CSAR which is actually 1 of its main role, Germany and we also use it for CSAR QUOTE(thpace @ Jan 10 2016, 01:00 AM) Aiyo.. troop deplyoment purpose. A ramp entrance win anytime against door. Something the ec725 does not have is a ramp More like resistance towards bullets and splinters eg RPG frag warhead. I'm sure its not for nothing EC725 invest 1 whole ton in armor and missile avoidance systems.Bo point talking armor.
