I'll give it to OP, I can't find the answer anywhere, either.
Wikipedia states that the m777 shoots at 827 m/s. Using this ballistic calculator, Here, and using 45 degrees angle and a 0 ft height, you get a flight time of 119.23 seconds, whick seems awfully long and not correct in the least. |

Depends on range. Direct fire a few seconds, out to 35km with a 155m a minute or so depending on meteorological conditions. 105s are similar, but max range with HERA/RAP is closer to 25km. With the M777EX cannons with a range of 70KM im hearing up to a couple minutes sometimes longer of hang time.

Quote HistoryQuoted: My brother was a 777 operator in Afghanistan for a couple of years. He said he had no idea since they usually fired them over mountains. He didn't care enough to count. But he said when they had to blast goat fuckers off the near mountains, it would usually take about four to five seconds to impact. If only they had access to something that told them exactly what the hang time was so he didn't have to count. |

Quote HistoryQuoted: Quoted: From my house I have seen them take around 30 seconds from the report of the howitzer to impact on the range. Damn. Didn’t know houses were built that close to a range. Well there isn't a lot to obstruct the view. You can hear the thump from inside, it sounds just like freedom, so sometimes I go out and watch. I see the smoke from the gun and count the seconds until I see the explosion. Then I count the seconds until I hear the report of the detonation and I can tell roughly how far away the impact point is from the house. It's great sport.

I always liked the Artty demo where one gun would fire a high angle round at a target, lower the barrel (wait, wait wait) fire a direct fire round at the same target and both rounds impacted simultaneously.

Quote HistoryQuoted: Damn. Didn’t know houses were built that close to a range. CEASE FIRE FREEZE! CEASE FIRE FREEZE! ALL UNITS CEASE FIRE FREEZE! ROUND OUT OF THE IMPACT AREA! Words you never want to hear at Graf. When you arrive, they show you photos of German houses destroyed by rounds out of the impact area. Even when they land in the range, you can hear the boom of the gun firing and the BOOM of the round impacting. ETA: The above meant some LT, possibly a CPT, and maybe even an LTC just lost their dental plans. Though it was funny when a 155mm round landed outside the impact area and every range including the .45 pistol range were also frozen. |

Depends where your target is, type of projo, and if the fire mission is high angle or low angle. You want max hang time? Short answer: over a minute.

Quote HistoryQuoted: If you’re the dude that stands their holding the extra increments over your head before the other dude pulls the lanyard you don’t necessarily need to know all that. True, on an artillery tube the FDC calculates that. However, if your sole focus in the military is as narrow as simply being on a gun crew, it isn't much to ask that you also know the capabilities and characteristics of your weapon system. Knowing the minimum/maximum time of flight potentials from shot to splash is kind of important even at the gun crew level as its how much time you have to prep before corrections come back, especially if you are looking to displace. |
