Pax Americana, Technological Readiness and broken weapons systems
Or "How we self-sabotage our starting positions for the next conflict, through unacceptable QC and wasteful Defense Spending"
Quote:
A $2.7 billion attack submarine, the USS Minnesota, has been out of commission for more than a year because of a defective pipe joint near the ship’s nuclear-powered engine.
The defective part, which is worth about $10,000, was installed near the ship’s nuclear power plant. Engineers discovered the poorly welded steam pipe in early 2015, and ongoing repairs have led to the ship being stuck in overhaul ever since, according to Navy Times.

lightweight is fashionable but ...
The term lightweight is a catalyst for all manner of projects intended to benefit military operations, for example the Combat Lightweight Automatic Weapon System (CLAWS) and the Lightweight Dismounted Automatic Machine Gun (LDAM).
http://www.thefirearmblog.com/blog/2...r-machine-gun/
recently highlighted a project – not apparently CLAWS but possibly LDAM - to develop a replacement .50cal MG for the classic .50cal M2 HB and as improved with QCB. Just possibly that project might be intended to also replace the derivative M3 with its higher maximum ROF.
The item’s reporter was unimpressed for several reasons not explained with all details on weights, although he did quote it is hoped to “save 16-pounds off of a 26-pound barrel”. As a summary of some of his concerns, the M2 which covers only part of the overall requirement for support MGs is bulky and with heavyweight tripod weights 128 lb, reducing to 106 lb with lightweight tripod. Keeping the M2 supplied with ammunition is burdensome – at about 28 lb for a 100-round belt without packaging - so it is often employed as a vehicle weapon. And when offloaded or back-packed by infantry it routinely needs logistic support from vehicles.
With the M2 in service as a reliable, well regarded and widely employed MG there is little point in spending development dollars on a new .50cal medium ROF MG or even just a lightweight barrel. A heavier barrel with less need for changing out on vehicles could be better value.
In somewhat the same vein the US Army has an Extended Range Cannon Artillery project to replace 39 calibre barrels by 52 calibre barrels in all its 155mm howitzers.

That is intended to increase their maximum reach of about 30,000 yd to about 50,000 yd. And it includes a 52 calibre barrel that will increase the 9,300 lb weight of the towed M777 howitzer by some 1,000 lb. The M777 was quite recently developed with a part titanium carriage to obtain lightweight heli-portable support fire. The concepts for deep battle may in addition to rocket and missile artillery and attack helicopters demand long range barrels on self-propelled howitzers. However, heavying up any of the M777s for intermittent and punishing high pressure use seems illogical.
The US Army must already have procedures to ensure redundant and nugatory projects are shut out or down at an early gate. But the gate guardians could be trapped in a procedural bog or have in some other way gone missing. If either of those circumstances apply it could be appropriate to start and promptly implement a higher level weight reduction project.
AAR for the F-35A - reduced but salvageable
There is potentially yet another problem with the F-35A CTOL variant of the JSF. For Air-Air Refuelling the F-35A has on its fuselage spine a standard US Air Force-style AAR receptacle designed to interface with the heavy flying boom of an aerial tanker. By contrast the maritime F-35B STOVL and F-35C CATOBAR variants for the US Marine Corps and US Navy are equipped with a retractable AAR elbow-probe designed to interface with a less heavy long hose-drogue towed by a tanker, or by a buddy fighter temporarily configured as an expedient tanker.
The refuelling boom carried by specialised tankers is subject to damage and malfunction due to slapping and ramming, and it can also damage the AAR receptacle on a receiving aircraft. However those large tankers typically have a boom and two underwing hose-drogue pods .On that basis and the redundancy factor implicit in twin hoses it is apparent that many receiver aircraft would be better secured and more employable if dual equipped with an AAR receptacle and an AAR probe.
There have been no reports of a version of the F-35A being either dual equipped or singly equipped with just an AAR probe. So those European and other forces which have traditionally employed buddy fighters and specialised hose-drogue - or boom and hose-drogue - tankers may be doing so knowing that acquisition of the F-35A CTOL will leave them with loose ends.
