У меня такая идея была лет 10 назад, но процессоры были еще слабоваты.

Мне, честно говоря, не очень нравится эта херня. Перемудрили. Уже есть коммерческие прицелы с лазерным дальномером, баллистическим калькулятором и метеостанцией. Он выносит прицельную метку куда надо, совмести и нажимай.

New Army artillery doubles attack range and outguns Russian equivalent

Operation Lightning Strike is a combined arms live-fire exercise that increases unit interoperability and synchronization in an effort to concentrate combat power on the battlefield.

The Army is fast-tracking an emerging program to engineer a longer-range artillery cannon able to out range enemy ground forces by hitting targets at more than twice the distance of existing artillery.
The service is now prototyping an Extended Range Cannon Artillery weapons with a larger caliber tube and new grooves to hang weights for gravity adjustments to the weapon – which is a modified M777A2 mobile howitzer.
Existing 155m artillery rounds, fired with precision from mobile and self-propelled howitzer platforms, have a maximum range of about 30km; the new ERCA weapon is designed to hit ranges greater than 70km, Army developers said.
“When you are talking about doubling the range you need a longer tube and a larger caliber. We will blend this munition with a howitzer and extend the range. We are upgrading the breach and metallurgy of the tube, changing the hydraulics to handle increased pressure and using a new ram jet projectile – kind of like a rocket,” a senior Army weapons developer told Wrrior Maven in an interview.
The modification adds 1,000 pounds to the overall weight of the weapon and an additional six feet of cannon tube. The ERCA systems also uses a redesigned cab, new breech design and new “muzzle break,” the official explained.
“The ERCA program develops not only the XM907 cannon but also products, such as the XM1113 rocket assisted projectile, the XM654 supercharge, an autoloader, and new fire control system,” an Army statement said.
As part of an effort to ensure the heavy M777 is sufficiently mobile, the Army recently completed a “mobility” demonstration of ERCA prototypes.
The service demonstrated a modified M777A2 Howitzer with an integration kit for the mass mock-up of the modified XM907 ERCA cannon at Yuma Proving Ground, Arizona.
"Their [user] concern is that when the self-propelled program is done they will be left with a towed cannon variant that they can't tow around, which is its number one mode of transportation," David Bound, M777ER Lead, Artillery Concepts and Design Branch, which is part of the Armament Research, Development and Engineering Center, or ARDEC, said in an Army statement.
The ERCA is currently being configured to fire from an M109a8 Self-Propelled Howitzer, using a 58-Cal. tube; the existing M109a7, called the Paladin Integrated Management, fires a 39-Cal. weapon.
ERCA changes the Army’s land war strategic calculus in a number of key respects, by advancing the Army’s number one modernization priority – long-range precision fires. This concept of operations is intended to enable mechanized attack forces and advancing infantry with an additional stand-0ff range or protective sphere with which to conduct operations. Longer range precision fire can hit enemy troop concentrations, supply lines and equipment essential to a coordinated attack, while allowing forces to stay farther back from incoming enemy fire.
A 70-kilometer target range is, by any estimation, a substantial leap forward for artillery; when GPS guided precision 155mm artillery rounds, such as Excalibur, burst into land combat about ten years ago - its strike range was reported at roughly 30 kilometers. A self-propelled Howitzer able to hit 70-kilometers puts the weapon on par with some of the Army’s advanced land-based rockets - such as its precision-enabled Guided Multiple Launch Rocket System which also reaches 70-kilometers.
In a modern threat environment, wherein near-peer and smaller-level rivals increasingly possess precision-guided land weapons, longer-range C4ISR technology and drone weapons, increasing range is a ubiquitous emphasis across the Army and other services. Russia’s violations of the INF treaty, new S-500 air defenses, new Armata tanks and fast growing attack drone fleet - all point to a growing need for the US to outrange and outgun potential adversaries.
In fact, senior Army developers specifically say that the ERCA program is, at least in part, designed to enable the Army to out-range rival Russian weapons. The Russian military is currently producing its latest howitzer cannon, the 2S33 Msta-SM2 variant; it is a new 2A79 152mm cannon able to hit ranges greater than 40km, significantly greater than the 25km range reachable by the original Russian 2S19 Msta - which first entered service in the late 1980s, according to data from globalsecurity.org.
Earlier this year, statements from the Ministry of Defence of the Russian Federation said that 2S19 Msta-S modernized self-propelled howitzers were fielded near Volgograd, Russia. The 2S19 Msta-S howitzers are equipped with an automated fire control system with an increased rate of fire, digital electronic charts, ballistic computers and satellite navigation systems, the report says.
Therefore, doing the simple math, a 70km US Army ERCA weapon would appear to substantially outrange the 40km Msta-S modern Russian howitzer.
While senior Army weapons developers welcome the possibility of longer-range accurate artillery fire, they also recognize that its effectiveness hinges upon continued development of sensor, fire control and target technology.
“Just because I can shoot farther, that does not mean I solve the issue. I have to acquire the right target. We want to be able to hit moving targets and targets obscured by uneven terrain,” the senior Army developer said.
Multi-domain warfare is also integral to the strategic impetus for the new ERCA weapon; longer range land weapons can naturally better enable air attack options.
Operating within this concept, former Army TRADOC Commander Gen. David Perkins and Air Force Air Combat Command Commanding General James Holmes launched a new series of tabletop exercises several months ago – designed to to replicate and explore these kinds of future warfare scenarios. The project is oriented toward exploring the kind of conflicts expected to require technologically advanced Army-Air Force integration.
In a previous Pentagon report, Holmes said the joint wargaming effort will “turn into a doctrine and concept that we can agree on.”
Such a development would mark a substantial step beyond prior military thinking, which at times over the years has been slightly more stove-piped in its approach to military service doctrines.
Interestingly, the new initiative may incorporate and also adjust some of the tenants informing the 1980’s Air-Land Battle Doctrine; this concept, which came to fruition during the Cold War, was focused on integrated air-ground combat coordination to counter a large, mechanized force in major warfare. While AirLand battle was aimed primarily at the Soviet Union decades ago, new Army-Air Force strategy in today’s threat environment will also most certainly address the possibility of major war with an advanced adversary like Russia or China.
​In fact, the Army’s new Operations 3.0 doctrine already explores this phenomenon, as it seeks to pivot the force from more than a decade of counterinsurgency to preparedness for massive force-on-force warfare.
Jumping more than 40 years into the future beyond AirLand Battle into to today’s threat climate, the notion of cross-domain warfare has an entirely new and more expansive meaning. No longer would the Air Force merely need to support advancing armored vehicles with both air cover and forward strikes, as is articulated in Air-Land Battle, but an Air Force operating in today’s war environment would need to integrate multiple new domains, such as cyber and space.
After all, drones, laser attacks, cyber intrusions and electronic warfare (EW) tactics were hardly on the map in the 1980s. Forces today would need to harden air-ground communications against cyber and EW attacks, network long-range sensor and targeting technology and respond to technologically-advanced near-peer attack platforms, such as 5th-generation stealth fighters or weaponized space assets.
In a concurrent related effort, the Army is also engineering a adaptation to existing 155mm rounds which will extend range an additional 10km out to 40km.
Fired from an existing Howitzer artillery cannon, the new XM1113 round uses ram jet rocket technology to deliver more thrust to the round.
"The XM1113 uses a large high-performance rocket motor that delivers nearly three times the amount of thrust when compared to the legacy M549A1 RAP," Ductri Nguyen, XM1113 Integrated Product Team Lead.” "Its exterior profile shape has also been streamlined for lower drag to achieve the 40-plus kilometers when fired from the existing fielded 39-caliber 155mm weapon systems."
Soldiers can also integrate the existing Precision Guidance Kit to the artillery shells as a way to add a GPS-guided precision fuse to the weapon. The new adapted round also uses safer Insensitive Munition Explosives.

Norway's Nammo has unveiled a potentially revolutionary concept for an air-breathing, ramjet-powered, pseudo-missile that any standard 155mm howitzer can fire at targets more than 60 miles away. The U.S. Army has already expressed an interest in just such a projectile, which could also end up in service with the U.S. Marine Corps, and the round might finally offer a way for the U.S. Navy to make use of the cannons on its new, stealthy Zumwalt-class destroyers.

Оборудовать артиллерийский снаряд прямоточным воздушно-реактивным двигателем собирались еще в прошлом веке - правда, тогда речь шла о калибре 406 мм для линкоров типа Нью-Джерси. В калибре 155 у меня сомнения - перегрузки при выстреле больше, значит двигатель должен быть массивным и особо прочным, да еще топливо с собой нести надо, а масса снаряда невелика, порядка 50 кг. На боевую часть ничего не останется...

главное, не победа, а участие... :mrgreen:
военмеховцы им. товарища Устинова который год подряд дрочат на эту 152 мм тему. Еще не мед, но говном уже не пахнет. Тезка, твоя теория неправильна, и вот почему. Счетаю, что для разгона до высоких скоростей, надо много усилий, а для поддержания высокой скорости - в разы менее того, не?[img][img][/img][/img]
