todo esto es entendible... en parte, menos el hachazo que le quieren meter a los marines
asi como van, un dia de estos lo van a eliminar del todo al cuerpo... sin F-35B, sin EFV, sin V-22, sin flota de predispocicion...
o sea....

Es mas o menos lo que dijo Gates. Que el Pentágono estaba pagando un huevo de plata por una capacidad de asalto y desembarco en playas defendidas que en realidad no se había usado desde Corea.

claro, una cosa es entrar en incheon a punta de plomo, pero la capacidad si se ha usado...
libano 82, desert shield, grenada, vietnam, somalia... solo las mas notorias
sin notar o meter desert storm (y la amenaza de desembarco en kuwait) haiti cuando aristide, y otras situaciones que cuando te ponian un CVBG y un ARG frente de tus costas es suficiente motivo para apaciguar los animos y la herramienta que hacen que escuchen a los EEUU...
imaginate de pasar a eso a pasar a lanchas higgins o RRC en una fuerza mucho mas enfocada a ayuda humanitaria o contraterrorista/contrainsurgente...
Raytheon Flies AESA Retrofit Radar In F-16
Dec 2, 2010
By Graham Warwick
An international customer could order the first active, electronically scanned array (AESA) radar upgrade for the Lockheed Martin F-16 in 2011, moving ahead of the still-undecided U.S. Air Force, Raytheon says.
The company has completed flight trials of its Raytheon Advanced Combat Radar (RACR) in a U.S. Air Force F-16D Block 50 at Edwards AFB, Calif. The six flights were conducted in July, but have just been announced.
Northrop Grumman flew its competing Scalable Agile Beam Radar (SABR) on an F-16 at Edwards in January, in support of a U.S. Air Force AESA feasibility study.
The July flights were the first time RACR had flown in any platform, says Ken Murphy, Raytheon business development manager. Northrop’s SABR previously had flown on the company’s Sabreliner testbed.
Murphy says the RACR went from concept to flight on the F-16 in 24 months because it is 90% common with the APG-79 AESA on the F/A-18E/F and the APG-82 being installed on the F-15E.
The Edwards flights demonstrated air-to-air and air-to-ground modes including high-resolution synthetic-aperture radar (SAR) imaging with ground moving-target indication overlay, he says. Air combat modes were demonstrated and the radar integrated with the F-16’s joint helmet-mounted cuing system.
Efforts to sell AESA upgrades to F-16 operators are picking up pace. “I think next year will be the turning point when international customers move ahead of the U.S. Air Force,” Murphy says.
USAF is looking at extending the service life of its F-16s because of delays to the F-35 Joint Strike Fighter, but has yet to decide whether to fund an avionics upgrade, he says.
Meanwhile, the companies have provided the U.S. government with pricing data requested by two countries that operate large F-16 fleets. “A couple of countries are seeking budgets [for upgrades],” Murphy says.
RACR deliveries could begin 36 months after contract award, paced by the development of radar modes required by the customer, Murphy says, adding that node development and testing would fit within the three-year timescale of the Common Configuration Implementation Program upgrade for the F-16C/D.
Cost of the RACR retrofit is comparable to that of upgrading the F-16C/D’s Northrop APG-68 mechanically scanned radar to the SAR-capable (V)9 standard, but the AESA offers a tenfold increase in reliability, Murphy says.
F-15E flies with new radar system

1/24/2011 - EGLIN AIR FORCE BASE, Fla. (AFNS) -- Officials took a step forward in the F-15E Strike Eagle's continuous technological evolution as the Air Force's most versatile combat aircraft here Jan. 18.
Officials from the 46th Test Wing launched the fourth generation fighter for the first time with a new and improved radar system, the APG-82(V)1.
The APG-82 uses active electronically scanned array radar technology composed of numerous small solid-state transmit and receive modules. The standard radar, APG-70, is a mechanically scanned array housed in the nose of the aircraft. Although the current F-15E radar has undergone numerous updates and upgrades, it is still the same system the aircraft had on its maiden flight more than 24 years ago.
"We've been able to get more out of it, but at this point it's pretty much maxed out," said 1st Lt. Nathaniel Meier, a radar modernization project manager with the Operational Flight Program Combined Test Force.
The new radar lacks the motors and hydraulics of the old system and includes a new avionics and cooling system.
Aircraft radar continuously sends out and receives energy to identify objects or targets around it.
Due to its unique capabilities, the F-15E radar operates as air-to-air and air-to-ground radar, officials said.
"One AESA-equipped F-15E can detect and track multiple targets simultaneously and gain the same battle picture and prosecute the same number of attacks that currently require several mechanically scanned radar assets," said Brad Jones, the Boeing director for U.S. Air Force development programs. "Adding AESA multiplies the effectiveness of the F-15E."
The advantage AESA radar has over an MSA is its near-instantaneous ability to redirect its focus from air-to-air to air-to-ground mode, officials said.
By no longer having to wait for the array to physically move to a new area of interest, the aircrew receives better situational awareness in less time, Lieutenant Meier said.
The four-year-old project borrowed from existing technology to create the new system. The array system was taken from F-15C Eagle models and the avionics were borrowed from F-18 Hornets.
The reason for the change was to improve the entire aircraft's reliability, availability and maintainability, Lieutenant Meier said.
The new radar works as a plug-in-play system with newer, easily replaceable parts, the lieutenant said.
It's expected to have approximately a 20-fold improvement in aircraft reliability, he said.
The aircraft also stays mission-ready.
An average failure for the radar component was previously measured in tens of hours and can now be measured in hundreds of hours, Lieutenant Meier said.
The APG-82 has fewer moving parts and the new equipment lasts longer, which cuts down on the time needed for repairs, he said.
The modification of the aircraft, which began in June 2010, was a concerted effort by members of Boeing, the 46th Maintenance Group, Raytheon, the 46th Technical Support Squadron and the OFP CTF.
"Without their determination, (F-15E) RMP would not have been anywhere close to making its first flight," Lieutenant Meier said.
The developmental test flight was considered successful, and the aircrew members said they liked what they saw during the flight.
"There are huge performance increases," said Maj. Raja Chari, a 40th Flight Test Squadron member and the pilot for the first flight. "We're getting the benefit of two decades worth of technology. From what we saw in this flight, we're heading in the right direction."
The developmental test process is about building incrementally into testing more complicated functions of the equipment and finding any flaws and problems based on usage in specific test profiles.
"Really, the engineers put in the time and hard work," Major Chari said. "We have the easy part of seeing if it will do what they thought it would. It was interesting to see the engineers reacting and diagnosing the issues right away, based on our feedback."
Capt. Chris Dupin, a 40th FTS member and the weapons system officer for the first flight, said he noticed improved capabilities during the initial flight.
He said the radar was able to detect F-16s much farther away than ever before.
"The kill chain for anything is the ability to detect, identify, target and engage a threat," Captain Dupin said. "If we can detect an air target earlier or farther away, that leaves more time and space to complete the rest of the kill chain. Completing the kill chain faster and earlier means we're better able to gain or maintain airspace superiority."
The biggest "test" facing the project involves combining avionics and array systems from other aircraft and incorporating them into a totally different one.
"By using (government and commercial) off-the-shelf equipment, the Air Force is able to save a large amount of the development costs, but the challenge is integrating these new systems and making them work as one," Lieutenant Meier said.
Developmental testing is scheduled to continue through 2012, but the OFP CTF, being a shared unit of the 46th Test Wing and 53rd Wing, is unique in that its members can perform developmental tests while incorporating early operational testing.
Officials have begun modifying a 53rd Wing F-15E with the new radar and they plan to begin some of the operational type of testing as early as March.
The next stage of testing for the radar will be conducted by Air Force Operational Test and Evaluation Center officials before being incorporated in all F-15Es beginning in approximately 2014.
