I always wondered, despite the size of Russian submarines, why does the Typhoon class, the largest ever built, is only capable of carrying 20 SLBMs? At first I thought that this was so because the SLBMs launched are of greater size and performance, but they are equal in size and performance when compared to the Trident II. I ask this because Ohio class Submarines that we use are smaller than Typhoons but carry 24 SLBMs, which gives us a major Retaliatory strike or First strike advantage. Why is this so?

Does anybody know by any chance how precise guns like the M61 or BK 27 for example are, i.e. what their spread is?
When for a certain rifle max spread is given, that means that half this value would be the distance between the aimpoint and the worst possible shot, correct?
If I have the spread for a certain gun, is there any rule where on target the impacts will be distributed statisticly? I.e. are they evenly destributed over the whole diameter of the spread, or is there some kind of a gaussian bell curve? I would assume the second true for the max spread but the first for the average spread.

From what I can remember from my ballistics module, there are several factors that affect the spread of a gun.
1. Wear and tear of the barrel, particularly for guns with rifling. This affects the efficiency of the gas pressure in helping to accelerate the projectile out the barrel, with implications for the muzzle velocity of the projectile. A badly worn barrel may cause the projectile to spin unevenly and hence "tumble" through the air, which makes it very inaccurate.
2. Muzzle velocity. A higher muzzle velocity translates to greater accuracy. Hence, rifles are accurate are longer ranges than pistols due to their higher muzzle velocity. This also means that higher muzzle velocity translates into a smaller spread.
3. Environmental conditions, particularly for long ranges. Wind affects the trajectory of projectiles in a small way. However, given a sufficiently long range, it can have a noticeable effect on the spread.
4. Calibration. If the gun is not calibrated properly to the aiming sight for the shooter, it isn't going to be particularly accurate, but the spread is unlikely to be affected. However, for a gun system that is computer controlled, and it is not calibrated properly (e.g., muzzle velocity), than the spread will be affected.
Thus, for the distribution of the spread, it depends on whether it is a rifled gun or a smoothbore gun. A rifled gun will have the spread skewed in a certain direction (can't remember which side) due to the spin on the projectile. And the spread varies with distance (because the projectile spins and does not travel in a straight line).
For a smoothbore gun, the spread should be centred on the aim-point for a properly calibrated gun under zero wind conditions. In such a case, it should be a Gaussian distribution for a sufficiently large sample size.
I have a PLA question that may have been asked previsouly.
1) Are enlisted men permitted to be married.? I ask because when I see PLA soldiers returning from their missions I see only officers re-uniting with their loved ones.
2) How top heavy with officers is the PLA? I see photos of officers doing jobs that enlisted men do in other services.
Thanks!
Nevermind...I found my answer!

In answer to your question #1, yes, absolutely.
Thanks solarz..but in reading the article I found it looks as though thay can only visit their families once a year for a month..I could not imagine that having served for 20 years and 15 of which I was married...Does anyone know if military dependents have any privileges similar to the US military? You know exchange, medical, dental, commissary MWR..etc..

I'm not sure how accurate the 1 month/year information is, but I would imagine that most young people would not stay in the army for more than a few years, in order to get some marketable skills.
Re: any info about 5.8mm type 88B GPMG
one universal 5.8 for suit all is totally disaster, the PLA planner seems forget or just try think instant, or undermined anything sound like old soviet style thinking. They lack understand that purpose every small created: sniper, MG etc.
they fancy about 5.8mm is up to them, but for sniper or MG better stick to 7.62x 54mm.
but 5.56mm and soviet M43 7.62mm are recommendable although rule against it, for combat effectiveness sake. After Iraq and Afghan lesson US start thinking using enemy ammo in battle, even they planned the some new AR will compatible with AK mags (for SF). PLA planner forget ancient war rule :war is about adaptive.
