Iraq
Watch bombs being dropped on ISIS in Mosul from the cockpit of a B-52

A heartwarming story, I know.
The venerable U.S. Air Force B-52 Buffs have been supporting the air war on ISIS since April 2016.

The Stratofortress strategic bombers, based at Al Udeid, Qatar, launched their first air strike against a Daesh weapons storage facility in Iraq on Apr. 18, 2016.

As already highlighted in a previous article, the USAF B-52s have mainly flown Close Air Support and Air Interdiction mainly delivering two types of JDAMs (Joint Direct Attack Munitions): the 500-lb laser-guided GBU-54s and the 2,000-lb GPS-guided GBU-31V3 "bunker busters" loaded onto the Heavy Stores Adaptor Beam pylons.

The typical loadout includes 3x GBU-31s and 8x GBU-54s along with PGMs carried inside the bomb bay of the B-52H Stratofortress. With the 1760 Internal Weapons Bay Upgrade the Buffs can carry up to 16 external laser JDAMs (8 per pylon) as well as 8 internal J-series weapons mounted on a conventional rotary launcher: a mix of PGMs that gives the Buffs the ability to deliver attack both stationary and moving ground targets.

In particular, the GBU-54s, that combines 500-lb Mk-82 warhead and the precision strike capability delivered by its dual Laser/GPS mode guidance system can be used against targets with reduced collateral damage.

For hardened targets or concrete shelters, the weapons of choice is the GBU-31s.The JDAM is a GPS aided inertially guided bomb. The Guidance and Control Unit (GCU) containing a HG1700 RLG, GEM-III GPS receiver and computer package is installed inside the bomb tailkit. The GCU is used on the bunker busting 2,000-lb class BLU-109/B forged steel penetrator warhead.

The GBU-31s are assembled at Al Udeid Air Base, Qatar, by airmen from the 379th Expeditionary Maintenance Squadron’s Munitions Flight. Considered that the base

The following video provides a really interesting point of view: it shows a high-altitude attack on a target in western Mosul (according to @obretix), as seen from the cockpit of a B-52 of the 23rd Expeditionary Bomb Squadron on May 23, 2017.

The detonation of the bombs as they hit the ground appears to be pretty huge.

I messed up the link above, here's the proper link abput the rudder: B-52 Rudder

Here's a picture showing how far from the fuselage the engines are. I think that #4 & 5 is fa enough away to give a good leverage arm for the powerful engines.

#6  Multi-engine aircraft number their engines from outboard port to outboard starboard. Number "1" would be the outermost engine on the left (pilot's) side, "8" would be the outermost on the right.

Yaw control would be most efficient (thrust:vertical axis pivot) using the outer engines (#'s "1" and "8") with efficiency decreasing as one worked toward the aircraft longitudinal axis (center).

Pilots may remember that "arm" thingie their IP's beat them over the head with.

Aside of that, I've got nothing.

Most likely it's for yaw control. The B-52 rudder is a bit on the small side, resulting in not being able to make turns very well. There was a B-52 that lost most of its vertical stabilizer, yet was able to fly and land with no problem.


I'm thinking the pilots used the #4 & #5 engines to supplement the rudder control, so by increasing/decreasing the thrust on those two engines, they can control the yaws.

#4  The GBU-31s are assembled at Al Udeid Air Base, Qatar

From what I read in the news, there seems to be a passion for bomb making in Qatar.

#3  Never flew anything bigger than a Cub, but I always assumed it was eubonics - or maybe it was ergonomics? - to help you find the center in the dark.

#2  I suspect 4,5 get reduced when releasing fuselage pylon mounted ordinance. But I don't know.

#1  BUFF's - What can't they do?



Do we have a Barksdale, etc maintenance person who can tell me why the controls for engines 4 and 5 on the throttle quadrant are higher than the rest? I'm thinking faster identification so as to use them at relative higher thrust at cruise, but...
