האמריקאים לא מאמינים במערכת הגנה אקטיבית של רפאל- מעיל רוח
רצ"ב כתבה על צרכי המיגון של צבא ארה"ב בעירק.
מערכת מעיל רוח לא נימצאת אפילו כאופציה , איינה ישימה , וגם לא בטוחה לסביבה
בו נשליך מכאן למציאות הישראלית - אין מערכת הגנה אקטיבית ישימה להגנה על טנקים ורק"מ אחר
זהוא לחץ של התעשיות להציג בשלות, בפועל המרחק רב ואולי עוד מיספר שנים תיכנס מערכת כזאת לשימוש כולל לימוד תו"ל והכשרת לוחמים למערכת שכזו .

U.S. Army: Active Protection Not Needed in Iraq
By GREG GRANT – Defense News 9/25/2006
The U.S. Army said its combat vehicles in Iraq do not need a high-tech defensive suite designed to shoot down rocket-propelled grenades (RPGs) because such weapons pose a minimal threat to soldiers, and because explosive reactive armor tiles and retrofitted steel cages are defense enough.
Crude but effective, roadside bombs remain the Iraqi insurgents’ favored means of attack, accounting for nearly 85 percent of them, said Maj. Gen. Jeffrey Sorenson, deputy for Army acquisitions, in testimony Sept. 21 before the House Armed Services tactical air and land forces subcommittee.
“Total RPG attacks on our combat systems is a very small percentage, and even with that small percentage, most of the attacks resulted in no damage to the vehicles, and there were zero [soldiers] killed in action,” Sorenson said.
Sorenson explained later that he was talking about attacks within the past year and a half on Abrams tanks, Bradley fighting vehicles and Stryker wheeled vehicles. He said RPG attacks had killed 10 soldiers inside those vehicles in the first year of the war.
He did not provide numbers of soldiers killed while riding in Humvees or other Army trucks, as the Army considers those vehicles to be incapable of mounting an active protection system.
Sorenson said recent media reports of the number of RPG attacks were overblown. In particular, he found “biased, unfair and truly disheartening” a Sept. 6 NBC news report that raised questions about a recent Army decision to award a contract to Raytheon to develop an active protection system as part of the service’s Future Combat Systems (FCS).
Defense News reported in April that the Army had passed on the Trophy active protection system, under development for more than a decade by Israel’s Rafael Armament Development Authority and Israeli Aircraft Industries, sparking lawmakers’ interest in the matter.
Raytheon did not have an unfair advantage, Sorenson said, nor did the Army “cook the books” in the active protection selection pro-cess. The industry team of Boeing and SAIC, along with the Army, chose Raytheon. “Raytheon was not allowed to participate in the source selection process,” he said.
Sorenson said the Army moved rapidly to field RPG defenses to its major combat vehicles in Iraq when the insurgency there accelerated in summer 2003. The Army fielded 1,097 sets of slat-armor cages for the Vietnam-era M-113 personnel carrier, and two brigade sets to its Stryker-equipped units. The bolt-on steel cages are designed to detonate the shaped-charge warhead of an RPG before it strikes the vehicle hull.
The Army has also fielded 950 sets of explosive reactive-armor tiles, small metal boxes that detonate to disrupt the effects of incoming weapons, for its Bradleys. Reactive armor sets for the Stryker will begin fielding next month, and for the Abrams beginning in June 2007.
Sorenson objected to media reports that the Trophy was a proven system, ready for fielding in Iraq. He said Trophy had not been “operationally validated” and would have to go through extensive Army testing prior to fielding.
He said there are at least 20 U.S. and foreign active protection systems in various stages of development. But few are capable of being fitted to the Army’s current battle fleet. He said the Trophy was not even the second or third choice in the Army’s selection process.
The Army picked Raytheon’s Quick Kill to equip current and future vehicles because it promised to defeat multiple RPG attacks from different directions and minimized the risks of injury or death to nearby soldiers or civilians, Sorenson said. Collateral damage to people near vehicles equipped with active protection, particularly in cities, remains the most daunting challenge in developing an effective system, Sorenson said.
All hard-kill active protection systems combine sophisticated fire-control radars and defensive munitions to blast incoming projectiles before they can hit the targeted vehicle. The Army chose Raytheon’s system in part because the defensive munitions pop up vertically, before rocket motors ignite, and fly out to intercept RPGs rather than shooting out from the sides of the vehicle, thus lessening the danger to nearby troops. •
