Originally wanted to call this “Xes and Os” (no resemblance to the pudgy Schneider offspring*) but it turns out the Army doesn’t call all their prototypes by an X prefix. Ah well – I learned something.<\/p>\n

The Army has given its Future Long Range Assault Aircraft Bell V-280 (their equivalent to a CV-22 Osprey) the official designation of MV-75, formerly YMV-75.<\/p>\n

In terms of the designation itself, the \u201cM\u201d stands for \u201cmulti-mission\u201d and the \u201cV\u201d refers to it being a vertical takeoff and landing capable design. The use of the \u201cM\u201d prefix for the baseline FLRAA variant is interesting given that previous Army transport helicopters like the Black Hawk and the Chinook have all had designations starting with \u201cU\u201d for utility or \u201cC\u201d for cargo. The \u201cmulti-mission\u201d designation here may, in part, reflect the baked-in special operations-specific features.<\/p>\n

Whether the number \u201c75,\u201d which is very much out of sequence with other known \u201cV\u201d designations, has any special significance is unknown. **Designation-Systems.net says that XV-25A, reportedly approved last year for the experimental tilt-ducted fan ARES drone, is the most recent in-sequence designation in that category.<\/p>\n

** It refers to the founding of the Army in 1775, per a<\/p><\/blockquote>\n

Think “Osprey with a racy fuselage” and you have a pretty good picture.<\/p>\n

The 101st Airborne Division, the Army\u2019s premier air assault unit, is set to be the first unit to get MV-75s. The 101st has already begun laying the groundwork to receive the future tiltrotors, which officials say will completely transform how it conducts operations, as you can read more about here.The War Zone<\/a><\/p><\/blockquote>\n

A bit heavier than originally specced so it can be easily adapted to special operations, the Bell V-280 has a top speed of 300mph, 2400 mile range, and effective combat range of 800 miles. Unlike the Osprey, the engine pods do not rotate, the rotors and drive shafts do. V-280 Wiki<\/a><\/p>\n

And the Army has also accepted the Sig-Sauer M-7, formerly XM-7, rifle. It uses an interesting cartridge, the 6.8×51. Now, gun types would probably assume it was just (in civilian terms) a .308 necked down to take a .270 bullet, right? Far from it – this uses a hybrid\u00a0 steel\/brass cartridge case and works at pressures of 80,000psi (compare that to its predecessor, the .270 Winchester, which runs about 62,000psi.) It launches a 150grain bullet 150fps faster than the .270, in a cartridge case which is short enough to fit in a medium (i.e. .308 action. Oh, and in the interests of lower cleaning requirements – it’s a gas-piston gun like the AK-47.<\/p>\n

As of last year, the Army said its \u201cacquisition objectives\u201d included the purchase of 111,428 M7s and 13,334 M250s.<\/p><\/blockquote>\n

There has been some controversy over this – an Army Captain Braden Trent has made some serous allegations about the weapon and cartridge<\/p>\n

\n

The Army infantry officer did his work while attending the Expeditionary Warfare School, part of the Marine Corps University in Quantico, Virginia.<\/p>\n

What is now designated the M7 has suffered from serious reliability and other issues, including having cartridge cases \u201cripped apart by the internal pressure of the system,\u201d excessive barrel wear, and regular breakages of key components, Trent stated. He claimed that these problems, together with a host of other factors, including the weight and recoil of the rifle, make the gun \u201cunfit\u201d for its intended purpose.\u00a0 The War Zone II<\/a><\/p>\n<\/blockquote>\n

Sig-Sauer claims CPT Trent is unaware of many mitigating engineering changes. One thing I would note – it is significantly heavier, 9 pounds with suppressor, than the M-4 it will replace, and its standard magazine holds 20 rounds (like an M-14.) So a combat load of 7 magazines will work out to 140 rounds, versus the current 210.<\/p>\n
