Скопирую несколько статей из Janes Defence Weekly и Janes Missiles & Rockets, правда без перевода. О том, что американцы задумали...

Май 2003 года:

The US Navy is about to start developing technologies that could
lead to a new supersonic cruise missile capable of being fired from
a variety of air, ship and submarine platforms.

Planned as part of the National Aerospace Initiative, the joint
effort is called the Revolutionary Approach to Time Critical Long
Range Strike Project (RATTLR) and includes the Office of Naval
Research (ONR), the US Air Force and National Aeronautics and Space
Administration.

The programme is part of the military's research into high-speed
expendable supersonic vehicles, said Lawrence Ash, the ONR's
programme manager.

RATTLR is envisaged as having two portions: the first involves the
study, design and development of vehicles that will conduct at least
three flight demonstrations within four years. The second part would
be to conduct a technology demonstration focused on developing the
technologies that could be used in future high-speed missiles or
flight demonstrations, but not necessarily the entire systems
themselves.

The demonstration vehicles are expected to have the ability to be
quickly developed into weapons compatible with aircraft like the
F/A-18E/F Super Hornet, F/A-22 Raptor and F-35 Joint Strike Fighter,
as well as from ship- and submarine-launched Vertical Launch System
(VLS) cells. The air-launched version would have a maximum weight of
1,800 lb (816kg) - to include a 500 lb payload - and is expected to
be a "medium-range weapon". The VLS variants would have maximum
launch weights of 3,400 lb, be capable of carrying a 750 lb payload
and have a longer range. A single variant compatible with both is an
option.

The vehicles will be capable of acceleration to a minimum cruise
speed of M3.0, which must be maintained for at least five minutes,
Ash said. Navy documents say that speeds of greater than M4.0 and
cruise times of more than 15 minutes are desirable.

Ash insisted that RATTLR is separate from another navy programme
called the Standoff High-speed Option for Counterproliferation
(SHOC), also an air-launched and possibly later sea-launched M3.5-
M4.5 400km-600km-range cruise missile (Jane's Defence Weekly 19
March). SHOC, Ash said, is focused on the near term, while RATTLR is
a longer-term science and technology development effort.

The ONR has begun an open search for potential contractors and
candidate technologies, with bids due in July. It is expected that
up to six contracts will be awarded starting in late September for a
single year, with additional yearly options. The ONR said that any
total contract would be worth a maximum of $175 million if all four
years' options were picked up.

Июнь 2003 года:

Boeing is in the process of developing the Harpoon 21, a follow-on
to the Harpoon Block II anti-ship cruise missile. Nine export
customers have adopted the Block II upgrade, which
added Global Positioning System/Inertial Navigation System guidance
and a land-attack capability to the Harpoon design and was optimised
for target discrimination in a littoral environment. Harpoon 21 is
intended to add to these upgraded capabilities. While Harpoon 21 is
being developed as a corporate initiative, Boeing hopes the US Navy
(USN) will be interested in developing the weapon.

Boeing funded development of the Harpoon Block II, but development
of Harpoon 21 will probably have to be funded as a USN programme to
be feasible, according to Jim O'Neil, Boeing's general manager for
naval weapons. Harpoon has been devised with current USN concerns in
mind. These include 'target selectivity' - the ability to hit
specific points on a target ship.

Improved post-launch control over the missile would enable the
launching platform or a standoff platform, for example a helicopter,
to transmit in-flight target updates to the missile while it is in
the air.

Boeing is considering using a version of the AN/AWW-13 advanced
datalink used on the Stand-off Land Attack Missile - Expanded
Response (SLAM-ER). Harpoon 21 would also use the mission computer
and planning system developed for the SLAM-ER. To reduce the
potential for collateral damage, Boeing is looking at warhead
modifications.

Since the end of the Cold War, the USN has not made updating its
Harpoon capability a top priority. It did not purchase the Block II
Harpoon upgrade, but retained its Block IC versions. It has not
committed itself to funding Harpoon 21 development, but over the
last year has shown more interest in the Harpoon, including the
weapon's potential employment as an armament option for the proposed
Littoral Combat Ship.

The potential for US Navy funding for Harpoon upgrades is in all
likelihood greater than it has been over recent years, but the
missile will require modifications if it is to be launched from the
Mk 41 Vertical Launch System aboard USN warships.

Пахать 1000 км на 4М это крутой движок должен быть. Может, они доработали-таки МА-31?

По поводу МА-31 - инфа от июня 2003 г.:

The US Navy has announced that it intends to buy an additional 25
Zvezda-Strela Kh-31A mod1 (AS-17) missiles from R&G International,
which it will convert into MA-31 supersonic sea-skimming target
drones. The navy retains the option to purchase a further 27
missiles, the announcement said.

И мартовская инфа про SHOC:

The US Department of Defense (DoD) is preparing a programme to
enable it to move closer to the goal of developing and fielding
long-range high-speed missiles potentially capable of striking time-
critical targets and defeating deeply buried bunkers. Both are
perceived as difficult challenges for current armed forces'
capabilities.

Called the Standoff High-speed Option for Counter-proliferation
(SHOC), the system would provide a short-term capability to
warfighters and be a stepping-stone to reaching an eventual goal of
fielding hypersonic missiles, said US officials. Many in the DoD
view hypersonic weapons as a promising means to help solve difficult
problems such as how to strike mobile targets as well as those
buried deep underground.

The SHOC, a proposed Fiscal Year 2004 (FY04) advanced concept
technology demonstration (ACTD) to be led by the US Navy, would be
conducted in conjunction with the Defense Threat Reduction Agency,
which is interested in the concept as a possible means to destroying
chemical and biological weapons concealed underground.

According to Capt Carl Reiber, the navy's programme manager for
standoff missile systems, the SHOC programme will initially focus on
developing an air-launched long-range missile capable of high
supersonic speeds of M3.5-M4.5 with a range of between 400nm and
600nm. Initially SHOC had a planned goal of M4.0-M6.0, Capt Reiber
said, but that has been revised following further studies.

The missile is intended to be no heavier than 2,000 lb (907kg),
allowing it to be launched from tactical aircraft such as the navy's
F/A-18E/F Super Hornet multirole fighter. The three-year ACTD
programme would produce "a few" prototypes to be test-fired and 10
residual missiles for emergency use, Capt Reiber said. If
successful, the effort would become a formal development programme
in FY07 and seek an initial operational capability in FY10-11.

While no formal production quantities have been finalised, Capt
Reiber said the navy is looking at producing 1,000 SHOC systems at
an estimated cost of $500,000 per missile.

The UK is also interested in joining the programme, contributing up
to 10% of the funding. The UK sees SHOC as a tie-in to its Future
Offensive Air System programme and the Selectable Precision Effects
At Range (SPEAR) concept. The US Air Force is another potential
partner and is studying the programme.

Although the SHOC is not yet a formal project and still needs
authorisation by the Joint Requirements Oversight Council, expected
by mid-year, it has successfully passed several reviews such as "the
breakfast club" - an informal group that considers ACTD proposals.

Boeing, Lockheed Martin and Orbital Sciences are all expected to bid
on the programme. MBDA is also expected to bid as a propulsion
subcontractor, most likely through a Boeing-led bid.

А им дадут?! :blink: :o


Конструууктоооор! Что они смогут из этого в принципе выжать?
И еще, кто додумался продавать такие ракеты США? Я как впервые эту ракету узрел на фото ТМ ~1993 г - влюбился сразу. Она была там самой красивой и по виду и по параметрам.

Ни дальность больше 300, ни скорость больше 4М выжать из [COLOR=red]этой[COLOR=red] конструкции в принципе невозможно.
Надо:
1. Проектировать новый движок с другой аэродинамикой и внутренней баллистикой
(это они могут,хотя чертежей им не продавали, но нам потребовалось 15 лет, из них 7-только на стендовые испытания)
2. Применять другие материалы, из титановых сплавов по пределу временной тепловой прочности выжато практически все.
(тоже могут, но .. будет очень дорого, у нас рассмативалась замена титана на сплав циркония с чем-то типа тантала, дальше бумаги это даже в СССР не прошло, слишком уж дорого)

>И еще, кто додумался продавать такие ракеты США?

Гораздо хуже китайский котракт, там им продали для БЕЗлицензионного производства всю документацию для производства Х-31П

Ситуация такова: В рамках первого контракта 1994г с MDD им поставлено 30 летающих машин + 4 бросковых макета
2 контракт (который с Боинг) 1999 предполагал поставку 100 летающих машин, но со сменой в РФ президента он был расторгнут с российской стороны, производственный задел (~15 штук) остался на заводе.
НО. В 1997 году американская сторона обратилась к нам с запросом об аттестации и продлении сроков гарантии примерно 40-50 Х-31А и П, оставшихся на Украине после распада СССР, им было сказано в том духе, что поскольку мы не знаем условия хранения последние 6 лет, то и гарантировать чего либо не может и вообще, "нефиг искать нахаляву на стороне подешевле, покупайте у нас"
Дальнейшую судьбу украинских Х-31 я не знаю, вполне может быть, что в связи с отказом РФ от 2 контракта амы их купили и сами провели периодику с аттестацией.

Да это довольно старые планы... Был такой проект еще с 90-х Fast Hawk/HyStrike, вот только сроки вск плывут и плывут вправо, то и программа то закрывается, то открывается новая...

Т.е. материалы головы не выдержат длительного нагрева что ли? Так это наверное решаемо. Вплоть до применения спец. ГО со сбросом. Вот ЦУ - это да, все заново

Я думаю, кидаться КР на 1 т. км. ФА и не должна...

Решаемо, да, но не в таких размерах, какие можно запихать на носители ФА

>Я думаю, кидаться КР на 1 т. км. ФА и не должна...

А кто должен? Раньше для этого были РСД и туева хуча Ту-16/22/22M3
Сейчас осталась только горстка Ту-22М3 на все-про все. То есть раньше у любого ком.округа и многих командармов был такой инструмент-сейчас его нет.
