Mosul 2017.

This is coolbert:

From the Strategy Page archive of Colonel Austin Bay we have this item.

"On Point"

"Mosul and Urban Warfare"

"On July 10, Iraqi prime minister Haider al-Abadi declared coalition forces had won a "total victory" in their fight to free the city of Mosul. Since June 2014, the unfortunate city had been occupied by ISIS terrorists."

"Abadi's claim of total victory was premature. In the following days, several small firefights erupted around the city. ISIS fighters reportedly entered a liberated village outside Mosul. Had they been hiding, planning to stage "stay behind" attacks on coalition forces? Or were they fleeing? Who knows. In city fights, flickering resistance may continue for weeks after the major battle is done."

Those many ruined buildings of Mosul offer excellent protection and hiding places for Islamic State "die-hards". Colonel Bay noting too the tactic of using "stay-behind" units organized in advance and capable of considerable mischief.

I HAVE REFERRED ON OCCASION TO MOSUL AS STALINGRAD IN THE DESERT. KEEP IN MIND THAT AFTER GERMAN SURRENDER AT STALINGRAD SPORADIC FIGHTING CONTINUING FOR TWO MONTHS. 20 % OF THE GERMAN FORCE RUSSIAN NATIONALS KNOWING FULL WELL WHAT GRIM FATE WAITED FOR THEM IF THEY GAVE UP TO THE SOVIET!!

F-89 Scorpion.

This is coolbert:

As was noted in the Strategy Page article referred to in the previous blog entry that accident rate of the American F-89 Scorpion exceedingly high. Monstrously so even!!

WARPLANES [F-89] DURING FLIGHTS DISINTEGRATING WITHOUT WARNING!

"The F-89C made its first flight in September, 1951, and the first operational F-89C squadron . . . received its first Scorpion on February 8, 1952."

ALMOST INSTANTLY F-89 WARPLANES INVOLVED IN CATASTROPHIC ACCIDENTS, WINGS JUST BREAKING LOOSE.

* "On February 25, an F-89C shed a wing."

* "On June 18 . . . the wing of one of the squadron's new Scorpions cracked and folded in flight"

* "On August 30 . . .  the left wing of one aircraft snapped off at the root."

* "another F-89C was lost to a wing failure on September 15th."

* "On September 22, still another F-89C . . .  [had] one of their wings fold up over their cockpit."

AND THE REASON FOR ALL THIS WAS?

T75 alloy as used in the fittings to attach the wing root of the airplane to the fuselage suffering from unexpected metal fatigue that cause for the warplanes disintegrating in flight!!

"The wing root is the part of the wing on a fixed-wing aircraft that is closest to the fuselage"

"[a] new aluminum alloy, T75ST, in the highly-loaded fittings where the wing's root was bolted to the fuselage. T75ST had promised high strength with low weight. A drawback, however, was that the fatigue characteristics of the new alloy under extreme conditions were not fully understood.

In addition:

"The final piece of the puzzle was the T75 alloy in the machined wing root fittings. The new alloy turned out to have unexpectedly high 'notch sensitivity,' meaning that any manufacturing imperfections, scratches, or dents could become origins for fast-spreading fatigue cracks."

F-89! You want me to fly what??

Accidents.

This is coolbert:

From an article as seen at the Strategy Page Internet web site we have some interesting statistics regarding warplane accidents.

"Attrition: The MiG-21 Curse Continues"

Emphasis not so much as problems with the Soviet era MiG-21 warplane but rather a comparison as to the accident rate of various military aircraft per 100,000 hours of flying time!

SINCE THE TIME OF THE END OF THE SECOND WORLD WAR COMBAT WARPLANES THEIR RELIABILITY MUCH GREATER, ACCIDENTS MUCH LESS.

You need to read it all!

"Combat aircraft have, for decades, been getting more reliable, even as they became more complex."

Consider also the comments of an acknowledged aviation authority regarding the issue:

"The more expensive--and scarce--the military planes [$100 million plus per copy] have become, the fewer hours the pilots fly them, the more the pilots are watched for deviations (unsafe flying, bad personal habits/character that could show a propensity for bad judgment), the tighter the mission requirements (no room for play), and the more carefully the planes are maintained and monitored.  No room for error.  Too expensive and rare to lose."

"You want me to fly what?"

RB-57.

This is coolbert:

Canberra RB-57 high-altitude reconnaissance aircraft from the era of the Cold War.

An aircraft with a ceiling for high-altitude photographic reconnaissance missions nearly equal to if not equal to the fabled U-2 "spy plane". This is all new to me.

"The Martin/General Dynamics RB-57F Canberra is a specialized strategic reconnaissance aircraft developed in the 1960s for the United States Air Force by General Dynamics from the Martin B-57 Canberra tactical bomber"

CANBERRA DESIGNATED AS WEATHER RECONNAISSANCE BUT MORE THAN THAT! DURING MUCH OF THE COLD WAR THIS WAS THE MAIN USAF STRATEGIC RECONNAISSANCE PHOTOGRAPHIC INTELLIGENCE WARPLANE? U-2 AS  FLOWN PURSUANT TO CIA MISSIONS, CANBERRA USAF!

B-57 as originally envisioned as a bomber a replacement for the B-26 medium low-level attack warplane!

Canberra as a bomber warplane to an extent in Vietnam replicating the role of the WW2 B-26, low-level attack mission mode. Yeoman duty primarily directed against the Ho Chi Minh Trail.

"As of 2015, three WB-57Fs are the only B-57 aircraft model still flying, in service with NASA.


Canberra "warplane" with civilian markings for NASA mission. "NASA 928 takes to the skies in 2005, carrying a special nose-mounted imaging system that helped NASA track and safeguard Space Shuttle Discovery during the STS-114 'return to flight' mission." Allegedly even active over Afghanistan in 2006.

Canberra I have always thought a warplane irrelevant to Cold War considerations. But I admit I was wrong!

CAS.

This is coolbert:

Two warplanes as being considered to replace the American A-10 ground attack close-air-support [CAS] aircraft.

One merely a concept, the other much more than that!

1. "The Machete: The Super Plane That Could Replace the A-10 Warthog (Or Not)?"

"Stavatti, the mercurial, Minnesota-based aerospace start up, has dusted off its old proposal for a new attack plane to partially replace the U.S. Air Force’s venerable A-10 Warthog."


Fires missiles and rockets, drops bombs, has the 30 mm cannon. Comes in either a jet or a turboprop drive version. That latter a pusher. At this exact moment a concept only on paper. Pilot only no weapons officer.

"The Machete, which is still just a concept, would come in two variants optimized for close air support — the propeller-driven SM-27 and the jet-propelled SM-28. Stavatti has proposed other variants of the Machete for air-to-air combat and advanced training."

2. "ARCHANGEL MANNED STRIKE"

"Archangel is a combat proven attack platform that fuses aircraft, crew, sensors, and weapons with long duration on-station times.  Archangel seamlessly flows between the Find, Fix, and Finish tasks on station, capable of employing GBU-12/58 Laser Guided Bombs, AGM-114 Hellfire, and CIRIT 2.75” Laser Guided Rockets."


Drops bombs, fires missiles and rockets. NO gun! Already in the air and flying. A two-seater, pilot and weapons officer.

CoS France.

This is coolbert:

From the BBC as reported the head of the French military has resigned!

"French military head de Villiers quits over cuts"

"The head of the French armed forces has quit after a clash with President Emmanuel Macron over budget cuts."

Key points with my comments:

" Gen de Villiers, 60, was infuriated by an €850m ($975m; £752m) cut in the military spending budget for 2017. Most was to come from cuts to equipment.

Euros, dollar, pounds! That figure of 850 Euros equal about to about ten of the most advanced French Rafale warplanes and no more.

* "President Macron wants to get the overall French budget deficit below a European Union cap of 3% of national income for 2017."

Only Norway and Australia of all the nations of the world having a budget surplus. All other countries strapped for cash, in debt, unable to pay their bills! France too! The European welfare state hard to sustain.

* "Furthermore, he [Macron] has pledged to lift the defence budget from 1.77% of GDP to Nato's target of 2% by 2025."

That 2 % goal as was agreed upon by all constituent members of NATO the French contribution cannot be made until 2025? If then? No wonder Donald is so mad at NATO!

920th PJ.

This is coolbert:

Supermen to the rescue! American supermen!

American Air Force pararescue jumpers [PJ's], graduates of "superman" school more than earning their keep.

A combined and extraordinary effort the results most gratifying.

"Rescue Airmen save two German citizens stranded at sea"

"PATRICK AIR FORCE BASE, Fla. (AFNS) -- In a concerted effort from July 7, and into the early hours of July 8, 2017, approximately 80 Airmen and four aircraft assigned to the 920th Rescue Wing successfully rescued two German citizens whose vessel caught fire approximately 500 nautical miles off the east coast of southern Florida."

Assets as deployed impressive and indicative of good teamwork. Fixed wing and rotary wing aircraft, mid-air refueling capability, etc.

It is not specifically mentioned and to me it is unclear whether the PJ's entering the water by parachuting or dropping from a low-flying helicopter. Pararescue personnel adept at water operations. And with good reason. 70 % of the surface of the planet is water.

GO PJ's. GO Air Force. Bravo!
