Modern Carrier Battle Group..Strategies and Tactics

Re: The End of the Carrier Age?

"...The wave pattern produced by an aircraft carrier at operating speed is highly specific. The fast container carriers of the sixties have been replaced by larger and slower ships so no other large ship comes near the speed of the aircraft carrier. ..."

Since a large tanker operates at about 16 knots, the carrier will not operate above that speed when within detection range of a passing satellite. After the satellite passes the carrier can sprint to maintain position

Re: The End of the Carrier Age?

It would be very suspicious, if on the next pass, the ship was found to be futher ahead than she should have been if she had been travelling at her supposed max speed of 16knots.

On the next pass the rotation of the earth would place that ship beyond the field of view of that satellite.

Where is NikeX If Iran can shot down stealth UAV RQ170 sentinel
Why not China with more sophisticated Air Defense.As I say before UAV is not magic weapon

The RQ-170 Sentinel is an unmanned aerial vehicle (UAV) developed by Lockheed Martin and operated by the United States Air Force (USAF). It has been deployed to Afghanistan as part of Operation Enduring Freedom.

Iran says it shot down unmanned US spy plane
By ALI AKBAR DAREINI | AP – 1 hr 59 mins ago


TEHRAN, Iran (AP) — Iran's armed forces have shot down an unmanned U.S. spy plane that violated Iranian airspace along the country's eastern border, the official IRNA news agency reported Sunday.

An unidentified military official quoted in the report warned of a strong and crushing response to any violations of the country's airspace by American drone aircraft.

"An advanced RQ-170 unmanned American spy plane was shot down by Iran's armed forces. It suffered minor damage and is now in possession of Iran's armed forces," IRNA quoted the official as saying.

No further details were published.

Iran is locked in a dispute with the U.S. and its allies over Tehran's disputed nuclear program, which the West believes is aimed at developing nuclear weapons. Iran denies the accusations, saying its nuclear program is entirely peaceful and that it seeks to generate electricity and produce isotopes to treat medical patients.

The type of aircraft Iran says it downed, an RQ-170 Sentinel, is made by Lockheed Martin and was reportedly used to keep watch on Osama bin Laden's compound in Pakistan as the raid that killed him was taking place earlier this year.

The surveillance aircraft is equipped with stealth technology, but the U.S. Air Force has not made public any specifics about the drone.

Iran said in January that two pilotless spy planes it had shot down over its airspace were operated by the United States and offered to put them on public display.

The Islamic Republic holds frequent military drills, primarily to assert an ability to defend against a potential U.S. or Israeli attack on its nuclear facilities.

Tehran has focused part of its military strategy on producing drones for reconnaissance and attacking purposes.

Iran announced three years ago it had built an unmanned aircraft with a range of more than 600 miles (1,000 kilometers), far enough to reach Israel.

Ahmadinejad unveiled Iran's first domestically built unmanned bomber aircraft in August 2010, calling it an "ambassador of death" to Iran's enemies.

Not necessary, it really depends on the orbit and whether the CVBG is on the East or West side of the orbit during the initial pass.

This illustrates that multiple platforms are needed for reliability. It does not say space-based SAR or a network of them is incapable. These are two very distinct ideas, but I see people keep trying to use the former to argue that the latter is true.

Since the aircraft carrier can launch and recover aircraft from zero speeds and up, tell us how ship speed will be a factor in detection of the carrier.

It isn't so much about position, but speed. Speed facilities aircraft launch and recovery. Lack of speed does the opposite and makes the entire operation very dangerous. Also, carrier sails into the wind, meaning ships that sailing into the wind are going to be high priority targets even if they were just traveling at 16 kts. Wind direction can be detected by satellites as shows.

How will this correction be done? In the world of radar detection this is considered a major problem.

And you expect such a major problem not to be addressed by the designers and engineers of such detection system? How convenient.

Let's wait until they show pictures and confirm it before we run with it.

Besides, the RQ-170, like most UAVs is not all that stealthy nor was it meant to be. It is also not really meant to be flying in contested air space. Any fighter that finds it would have an easy time of it...and if it was seen by any half-way sophisticated SAM, they could get it too.

I would not compare the loss of an RQ-170...even if it is confirmed, which it hasn't been yet, with the ability to detect, acquire, target and hit a CSG thousands of miles away.

Click the link that I provide look stealthy to me it has picture in it . As they say stealth is 80% shape

We all know what RQ-170 looks like and as a flying wing it's obviously "stealthy" but it is a very low end stealth compared to the likes of X-47B. Clearly RQ-170 was designed with not too high end VLO in mind knowing they would likely lose aircraft.

And how is the supposed shooting down of a Sentinel relevant to the previous discussion?

The key word is "if". Iran says alot of things but Iran is short on backing up what they say. As others have said, why don't we wait until we have some evidence such as the wreckage of this drone before we jump to conclusions as to what Iran has done.

Care to elaborate how is Sentinel different from X-47B in term of stealth . I just reply to the NikeX assertion that the answer to ASBM is stealthy UAV, UCAV

His vision is there will hundred of this UCAV flying 1000 km with impunity inland and hovering at each of the ASBM launch site ready to fire the missile
