XM8 Rifle Program in Trouble? 'Sources Sought' Notice Issued.  
 
 by David Crane
david@defensereview.com

US Army ARDEC, AMSTA-AR-PC, and Picatinny Arsenal (NJ) have just issued a Sources Sought Notice for a "Non-Developmental multi- configurable 5.56mm modular weapon system". It's possible that this notice is specifically designed to save/salvage the HK XM8 development program, in which the US Army TACOM-ARDEC and Picatinny Arsenal already have a significant time and money investment.

It's DefRev's understanding that the XM8 recently failed a US Army test (unconfirmed). It apparently suffered some kind of mechanical problem (unconfirmed). It's also been reported that the XM8 overheats when fired (presumably extensively) on full-auto (handguards melting and such). We don't know if this is true, either. We've been told that the US Marine Corps (USMC) doesn't want it (unconfirmed). So, it would seem that the XM8 development program is in serious trouble, at the moment. Several of our sources have even gone so far as to say the XM8 is dead. This is, as yet, unverified. We'll see. Even if this is true, for the moment, US Army programs have a way of coming back from the dead, on occasion.


Parece que o problema do calibre está fora de causa. O cartucho Mk262Mod 1 estará para ficar. Os cartuchos 6.5 já não devem ir para a frente.
Espero que mantenham tudo o que a XM8 tinha de bom. Mas os cámones estão a protelar tudo! Estão a ficar piores que nós, vejam bem...
Ai de ti Lusitânia, que dominarás em todas as nações...

Isto tudo para quê? Para nao deitar as 5.56mm em stock para o lixo?

Tsc tsc... e o pior é q está tudo na mão deles...

Esta era um pouco previsível penso eu... bastou olhar para a arma.

Também disseram que o AUG derretia... com 34 (36) carregadores de 30 tiros disparados em sucessão rápida e sem parar...
Para ter que fazer isto (disparar mais 1020 tiros seguidos) é porque se está numa situação desesperada!

Mas se alguém souber de alguma coisa sobre tais testes partilhe-os connosco!
Ai de ti Lusitânia, que dominarás em todas as nações...

Teria sido a versão SAW que derreteu (se derreteu)?
Uns poucos Beta C seriam suficientes para tal se não fizesse cook off antes do tempo.
Mas também fazer uma SAW de uma XM8 parece-me tonto...

"This just in: DefenseReview has been told by one of its sources that FN Herstal's/FNH USA, Inc.'s SCAR/SOFCAR (Special Operations Forces Combat Assault Rifle) competition winner utilizes an updated/upgraded FN FNC upper receiver w/M1913 Picatinny rail system, mated to a modified M4/M4A1 Carbine-config/type lower receiver. Supposedly, the M4/M4A1 Carbine-config/type lower features an HK M4 (a.k.a. HKM4) carbine-style flared mag well (magazine well). At this point, this information is unconfirmed/unverified. In other words, it's just a rumor, at present, albeit from a trusted source.

If the the above information proves to be true, however, it makes some sense. The FN FNC assault rifle and its Swedish cousin, the AK-5/CGA5 assault rifle (manufactured under license by Saab Bofors), represent a proven system that's known to be reliable under adverse conditions, from jungle, to desert, to arctic environments. This is because the FN FNC and AK5/CGA5 are based on the AK-47/AKM (Kalashnikov) operating system, which can handle dirt, mud, sand, etc., no problem. The only negative DefRev's ever heard about the FN FNC is that the firing pin tends to break prematurely, but this problem can be easily corrected.

This story is still developing, as new information continues to come in. The reason everything is rumors and innuendos right now is because SOCOM and FN Herstal/FNH USA, Inc. (under orders from SOCOM) are both... "

 :shock:

Lá se vão os plásticos!


Entretanto...

"For background, here's the original PRESOL (Presolicitation) Notice "Description" for the USSOCOM SCAR/SOFCAR (SOF Combat Assault Rifle) requirement (as it originally read):

"The United States Special Operations Command is issuing a solicitation for the procurement of SOF Combat Assault Rifles (SCAR). The program will use full and open competition to fulfill the joint USSOCOM SCAR requirement. The SCAR will be developed in two threshold configurations, a SCAR-Light (SCAR-L, 5.56x45mm) and a SCAR-Heavy (SCAR-H, 7.62x51mm) with the SCAR-L being the priority.

Both the SCAR-L and H will possess the capability for barrel modularity and thus will be available in the following variants: Standard (S), Close Quarters Combat (CQC) and Sniper Variant (SV). The SV can be a modular enhancement or a separate weapon. The barrel modularity can be accomplished via complete upper receiver changes or just the barrel. The SCAR-L shall be optimized for 5.56x45mm and thus shall use an enhanced 5.56mm magazine. The SCAR-H will provide an open architecture design to accommodate changing calibers from the standard 7.62x51mm. The initial caliber change is projected as the 7.62x39mm.

The ergonomic and parts commonality between the SCAR-L and H shall be maximized to create a family of SCAR weapons. This commonality is essential for training time reduction, enhancing mission effectiveness, and improving the SOF operator's ingrained operational and emergency procedure autonomic responses that are critical during high stress situations. The SCAR system will be rugged, highly reliable, controllable in full automatic fire, have no unsafe failure modes, be highly ergonomic, corrosion proof (objective)/resistant (threshold), capable of lube-less firing (objective)/minimal lube firing (threshold), and capable of being operated and maintained by a single man.

The SCAR-L with stock collapsed or folded shall not exceed lengths of 29.9"/33.6" extended with standard barrel. The SCAR-L shall weigh no more than 7.25 lbs unloaded. The SCAR-H shall be collapsible or foldable to lengths not greater than similar configurations of currently available 7.62mm battle rifles (30.3" folded/40.2" extended with standard barrel). The SCAR-H shall weigh no more than 9 lbs.

The following are the Key Performance Parameters for the SCAR: Adaptability, Modular/Family of Weapons, Reliability and Accuracy. The SCAR barrels/caliber will be readily exchanged at operator level, without head space/timing adjustments, within 20 minutes, threshold (T), 5 minutes objective (O). The SCAR-L and H, in threshold caliber configurations (5.56mm NATO and 7.62mm NATO) with M855 and M80 ball ammunition respectively (T), spirally developed/alternate caliber configurations (O), shall have a Mean Round Between Stoppages (MRBS) of 2,000 rounds (T), 8,000 rounds (O). The SCAR-L and H, in threshold caliber configurations (T), spirally developed/ alternate caliber configurations (O), shall have a Mean Round Between Failure (MRBF) of 15,000 rounds (T), 35,000 rounds (O). The SCAR-L and H, in threshold caliber configuration/ball ammunition (T), spirally developed/alternate caliber configurations (O), will have a fully functional service life without overhaul for a minimum of 15,000 rounds (T), 90,000 rounds (O) for the weapon and 15,000 rounds (T), 35,000 rounds (O) for the barrel. The SCAR, in threshold configuration (T) and all caliber/barrel configurations (O), will not add more than 1.0 MOA at 300 meters (T), .25 MOA at 300 meters (O) to baseline (M855, MK262, M80, M118) ammunition performance.

The SCAR shall also be compatible with the SOPMOD Accessory Kit components via MIL-STD 1913 rails. It is envisioned that the SCAR weapons will be available with a sling, bipod, forward handgrip, blank firing capability and an operator's manual. Offerors will be required to provide product sample SCAR-Ls as part of the proposal. The product samples will consist of 3 each SCAR-L rifles with standard barrels, 1 each CQC conversion and a SCAR-H technical approach.

After evaluation, the government will have the flexibility to award multiple contracts for follow-on test/evaluation quantities. The contract type will be an eight-year, Firm-Fixed Price Indefinite Delivery/Indefinite Quantity (IDIQ). The minimum quantity is projected to be 12 each SCAR-L Engineering Test Units with standard length barrels, 6 SCAR-L CQC conversions, 1 each SCAR-L Sniper Variant and 1 each SCAR-H standard.

The government will conduct an evaluation of the test units that may result in subsequent delivery orders for the SCAR family of weapons. The contract(s) minimum quantities are delineated above. The contract(s) maximums are 84,000 SCAR-L Standard; 28,000 SCAR-L CQC conversions; 12,000 SCAR-L SV; 15,000 SCAR-H Standard; 7,000 SCAR-H CQC conversions; and 12,000 SCAR-H SV. The contract will contain a Provisioning Item Order (PIO) contract line item number (CLIN) of $10,000,000 for both the SCAR-L and SCAR-H. The contract will also contain a CLIN for Engineering Services for product improvement/caliber modularity development for a not to exceed amount of $4,000,000. The contract will also contain CLINs for magazines and tool and gage kits for both the SCAR-L and SCAR-H. The contract will also have provisions for ordering technical data. The contract is F.O.B. Destination (NAVSEA Crane - Crane IN).

For the minimum quantities delineated above the delivery is required 180 days after order. Subsequent deliveries of the SCAR-L will require deliveries to commence 90 days after order. The delivery schedule for the SCAR-H is 180 days after order for the first deliveries and once in production will be 90 days after order. The ordering parameters (quantities) for all SCAR variants and magazines are a minimum quantity of 10/ea and a maximum quantity of 20,000/ea. The maximum monthly delivery rate is 2,000/ea for the SCAR L weapon type and 500 per month for the SCAR H weapon type. The solicitation will require delivery of 3/ea SCAR-L (5.56x45mm) product samples; 1/ea SCAR-L CQC conversion and a SCAR-H approach included in the concise technical proposal by the closing date of the proposal.

The solicitation will be evaluated on a best value basis and the Government will reserve the right to award to other than the lowest priced offeror and other than the highest technically rated offeror. The SCAR L product samples are not required to meet the specification in its entirety. The technical proposal shall address any differences between the product samples and the production units; must address any known deficiencies where the product samples do not meet the specification; and shall have a separate section addressing the vendor?s SCAR-H approach. The Government cannot guarantee the condition of the product samples after testing. All responsible sources may submit a proposal, which shall be considered by the agency.

All offerors are responsible for monitoring the Federal Business Opportunities website at http://fedbizopps.gov/ for release of the upcoming solicitation and any notices. Any questions may be directed in writing, to the following: pfender_j@crane.navy.mil or via facsimile to the attention of Mr. John Pfender at (812) 854-5198."

Description:

Pre-Solicitation Notice for the Objective Individual Combat Weapon (OICW) Increment I family of weapons

Solicitation No. W15QKN-05-R-0449

The U.S. Army ARDEC, Picatinny Arsenal, NJ 07806-5000, on behalf of the Program Manager for Soldier Weapons (PM-SW), has a requirement for a non developmental family of weapons that are capable of firing U.S. standard M855 and M856 ammunition. The family consists of a Carbine, Special Compact (SC), Designated Marksman (DM), and Light Machine Gun (LMG) weapon systems. This endeavor will be conducted in three phases consisting of a System Design and Development (SDD) Phase, a Low Rate Initial Production (LRIP) Phase and a Full Rate Production (FRP) Phase.

The Carbine, SC and DM weapon systems shall share at least 80% parts commonality and shall share at least 50% commonality with the LMG. Each weapon system shall be equipped with a Multi Purpose Sighting System (MPSS) enabling the warfighter to rapidly and effectively engage stationary and moving targets both with reflexive fire at close ranges, and with precision fire out to the maximum effective range of the variant (Carbine-500m, SC-150m, DM-600m, LMG- 600m). All OICW Increment I weapon systems shall incorporate a resident limited visibility fire control with infrared aim light, illuminator and visible red laser pointer. The infrared aiming light and illuminator shall be greater than, or equal to the capability of the AN/PEQ-2A.

A properly zeroed OICW Increment I Carbine (zeroed to 300 meters), SC (zeroed to 150 meters), DM (zeroed to 300 and 500 meters), or LMG (zeroed to 300 meters) shall enable a warfighter firing from varying fighting positions, both supported and unsupported to engage E-type silhouettes under conditions that include target exposure times from 3 to 8 seconds and targets moving 2 to 4 meters per second to the following metrics: Carbine (moving targets to 300m) with a Probability of Hit greater than .60 at 150m; SC (moving and stationary targets) with a Probability of Hit greater than .40 at 100m; DM (stationary targets, zeroed to 500m) with a Probability of Hit greater than .50 at 500m; LMG (Hit on first 6-round burst against a single E-type silhouette in an 8 target array, zeroed to 300m) with a Probability of Hit greater than .04 at 600m.

The OICW Increment I Carbine, SC and DM shall demonstrate 18,000 Mean Rounds Between Essential Function Failure (MRBEFF) for Class III malfunctions (i.e., for non-operator correctable malfunctions which cause the loss of essential OICW Increment I functionality) and 2,300 MRBEFF for Class I and II malfunctions combined (Class I malfunctions are operator clearable within 10 seconds, whereas Class II malfunctions require more than 10 seconds but less than 10 minutes to clear but can be corrected by the operator with available equipment). The OICW Increment I LMG shall demonstrate 18,000 MRBEFF for Class III malfunctions and 1,900 MRBEFF for Class I and II malfunctions combined.

The OICW Increment I Carbine, SC, DM weapon systems shall have a sustained rate of fire greater than or equal to 45 rounds per minute without degrading reliability. The OICW Increment I LMG weapon system’s sustained rate of fire shall be at a minimum of 72 rounds per minute for ten minutes without degrading reliability and accuracy.

All OICW Increment I weapon systems shall have a minimum barrel life of 15,000 rounds.

All Proposals will include written submissions and test (bid) samples, both of will be 60 days after Solicitation release. A pre-solicitation or a pre- proposal conference will be conducted at a later date (to be determined).

The offeror shall submit four (4) of each variant for a total of sixteen (16) complete weapon systems, along with sufficient spare parts, to the Government for bid sample testing no later than the closing date of the solicitation. Should an offeror’s bid samples pass through the initial and subsequent go/no go screening criteria, the samples will be evaluated with live fire to demonstrate the weapon systems’ ability to meet the system requirements.

The winning offeror will be awarded a contract for test quantities to proceed to a Milestone C decision, if required. After satisfying the requirements for a Milestone C decision, Low Rate Initial Production (LRIP) quantities (up to 4,900 weapon systems) shall be produced. Subsequent to the production of LRIP quantities, the Government may award multiple Full Rate Production (FRP) options to the winning offeror (up to 134,500 total weapon systems if the total number of options are exercised).

The OICW Increment I family of weapons is intended to replace current weapon systems to include the M4, M16, M249 and selected M9 pistols for the active army.

A Request for Proposal (RFP) to be posted on the TACOM-ARDEC Acquisition Center website located at: http://procnet.pica.army.mil is planned for release on or about 23 March 2005. Proposals, along with sixteen (16) bid samples, are required to be delivered within sixty (60) days from the date the RFP is released. Point of contact for this requirement is Mr. David DeCandia, Contract Specialist, AMSTA-AQ-APD, BLDG 10, Picatinny Arsenal, NJ 07806-5000, email: decandia@pica.army.mil, telephone number: 973-724-4674."
