Logic suggests that a 46t tank can't be as well armoured as a 65-70t tank.

A low speed turn will inevitably involve high AoA though, the lack of speed has to be compensated for by AoA, but yes at lower AoA the C will likely generate more lift because that is basically a carrier landing scenario.
-
I don't think it's that simple, I don't think Cl or Cl/Cd would just remain the same for a larger wing, I see the variable deteriorating as it gets larger. Compound that with increased weight and I see the Rmin being similar. I also see the smaller wing delaying separation more successfully at higher AoAs relative to size and if you look at the inner LE on the A/B you will note a significant difference vs the C.
-
But what does it say with respect to Cl/Cd vs AoA? True but air battles are not fought at airshow altitude and dropping that much energy would be foolish. Rmin also tends to be lower speed than max STR/ITR, which is what really makes the difference.

Has it fired the AMRAAM from internal bay upside-down yet?

Not quite that simple either, lower AoA means lower Cd but the C has more wing area, so the CdA product may be the same or higher, and the extra weight combined with the extra drag will reduce the ability of the thrust to act in the lift and turn directions. There's also nothing to say Cl or Cl vs AoA will be the same for a different sized wing. All that's likely to be true is lower T-O and landing speeds because it's a carrier aircraft and was therefore probably designed that way. To put the thrust drag relationships in some perspective, the specifications for the F-35A M0.8-M1.2 were downgraded by only 8s but for the C they were downgraded by 43s. So there is clearly a weight and drag penalty for the C.
-
For a given radius the speed of the A can be approximately 10% higher, so the rate will also be higher. The C will be able to perform tighter turns due to lower speeds but not at the same rate. TWR also plays a part here due to alpha and the C is significantly heavier, therefore the thrust component of acceleration in the turn and climb direction will be lower.

http://defense-update.com/20170626_laser_apache.html Apache Helicopter Fires High-Energy Laser Against a Ground Target at White Sands By Tamir Eshel - Jun 26, 2017 15500 Share on Facebook Tweet on Twitter A high-energy laser mounted on an Apache AH-64 attack helicopter acquired and hit an unmanned target during a recent firing test at the White Sands Missile Range in New Mexico. The test was conducted by Raytheon and the U.S. Army Apache Program Management Office, in collaboration with U.S. Special Operations Command. Illustration: Raytheon For the test, Raytheon coupled a variant of the Multi-Spectral Targeting System, an advanced, electro-optical, infrared sensor, with a laser. The MTS provided targeting information, situational awareness, and beam control. The system tracked and directed energy on a stationary target at a slant range of 1.4 kilometers. It was the first time a fully integrated laser system successfully shot a target from a rotary-wing aircraft over a wide variety of flight regimes, altitudes, and airspeeds, proving the feasibility of laser attack from Apache. For the test the laser was coupled with a variant of the Multi-Spectral Targeting System (MTS) to form a laser weapon pod that could acquire, track and engage the target. Photo: Raytheon The data collected from the test, including the impact of vibration, dust and rotor downwash, will help shape future high-energy laser systems. Modern, solid-state lasers are more useful for military applications as they become more powerful and compact. Podded versions such as the one tested on the Apache could be used on other helicopters in the future, enabling special operations forces and other operators to use kinetic effects with higher precision and lower risk of collateral damage. -
The C has lower g limits though, which might not be a big factor at high altitude but during air display demos it will.

Indeed, especially with a .338 that's only rated at 1,600m. Accurate calculation at these ranges is a fairy tale. Rob Furlong's kill also took 3 shots. I think in this instance it helped that he was firing on a militant group, so there were several targets together.
-
But equally, firing into a crowd of people from long range makes a hit more likely. Even if you don't hit the person you're aiming for, you'll probably hit someone.

Oh for sure, both impressive, but what about a shot from >2km using iron sights with an out-dated K31 rifle with Swiss 7.5x55mm rounds. https://indiansforguns.com/viewtopic.php?p=249107#p249107

And the flight time must be around 10s, so you kind of have to guess the target's movements over a full 10s, or hope they stay exactly still, hope the weather remains the same for 10s, hope the wind remains the same over 3.45km for 10s etc.

If we include rifles up to 120mm calibre, the record is still 5.2km. Also, repost. https://forums.eagle.ru/showpost.php?p=3175652&postcount=1332

I saw something about one for the Avenger drone.

AIM-120 can be fired LOBL too.

Sources say a member of Joint Task Force 2 killed an Islamic State insurgent with a McMillan TAC-50 sniper rifle while firing from a high-rise during an operation that took place within the last month in Iraq. It took under 10 seconds to hit the target. “The shot in question actually disrupted a Daesh [islamic State] attack on Iraqi security forces,” said a military source, who stressed the operation fell within the strictures of the government’s advise and assist mission. “Instead of dropping a bomb that could potentially kill civilians in the area, it is a very precise application of force and because it was so far way, the bad guys didn’t have a clue what was happening.” -
So when's it coming to DCS?
