Re: Small Arms Thread
I don't begrudge the IA better arms. I only resent their (to me) cavalier attitude when actually making the selections. There seems to be no long term plan, no research. The IA has thousands if not 10 of thousands of people working in machine shops and armories. They have a budget of 10 of thousands...

Re: Small Arms Thread
Shouldn't the IA have thought about it BEFORE changing to 5.56? After all they are the professionals! They told us they needed the 5.56 because it had better terminal ballistics amongst other best of brochure characteristics. Heck right here in the forum everyone in favour of the change stated the s...

I'm very sure that's not it. IIRC One of the reasons to justify the calibre change was the 7.62x51 had terminal ballistics which penetrated flesh but did not cause great wound damage before passing through the body. The justification for 5.56x45 was that it's terminal ballistics caused it to tumble ...

Too true. Someone may have seen the brochure for the Baretta ARX160 and sent that onwards and upwards to an RFP. Eventually the ARX 160 ended up as the ARX 200 for the 7.62x51 calibre. Presently the ARX 160 can only do 5.56x45 and 7.62x39 and ONLY with a complete Barrel + Bolt + Lower receiver chang...

The "airflow" is the headwind (either due to the movement of ship or natural wind blowing or both), flowing horizontally; when the a/c takes off, this wind hits the bottom of the wing surface. Because of this, apart from the normal lift, the wing produces additional lift like that of a ki...

Re: INS Vikrant News and Discussion
Moving on from blather, my main point still stands.
If an EMALS can be added to a ski-jump, you can get the required velocity and AoA from a shorter take-off run leaving the landing strip free for another waist located EMALS and a pocket sized USN type carrier - amongst other options.
