Winging It

Winging It: "

Selex Galileo is aiming for first flight of' a beefed-up version of its Falco unmanned aerial vehicle - known as the Falco Evo - by the end of the second quarter of 2010.

Attempting to gain maximum improvement in performance for a comparatively modest outlay, the company is using the Falco fuselage, but wedded to a larger wing and extended tail booms.

The basic Falco is already in service with Pakistan - though the company declines to identify Islamabad as the launch customer - while discussions are also continuing with Libya.

Four prototype ship-sets kits for the Falco Evo upgrade are now being manufactured. The design is intended to increase the basic Falco’s maximum take-off weight (Mtow) by 330kg (728lbs). The Falco Mtow is 420kg while the Falco Evo target is a 750kg Mtow. Maximum payload would be increased from 70kg to 120kg. Max endurance for the Falco Evo is projected to be 18-20 hours compared to 8-14 hours for the basic Falco.

'

Selex is also continuing work on expanding the payloads available for the Falco family, with radar and electronic warfare packages at varying stages of development. The company’s PicoSAR synthentic aperture radar (pictured above) 'will be flown on the UAV later this year, while an electronic surveillance measures package will be tested on the UAV in 2010.

Marines sack four over deadly plane crash

Marines sack four over deadly plane crash: "The Marine Corps has sacked four top officers of a California-based fighter squadron over the December crash of a fighter jet that slammed into a San Diego neighborhood, the service said Tuesday. Deferred maintenance and faulty decisions by the pilot and squadron members on the ground contributed to the crash, an investigation concluded. Two adults and two small children died when the jet hit their house.

Passing asteroid 'not something to worry about'

(CNN) -- You had a close encounter with a 40-yard-wide asteroid this week, but the astronomer who first spotted the large rock said it's nothing to worry about.


An asteroid (inside circle) passed within 38,000 miles of Earth on Monday.

Asteroid 2009 DD45 on Monday passed within 38,000 miles of Earth, less than twice the height of the geostationary satellites we depend on for communications, according to Robert McNaught of the Australian National University.

McNaught, who watches for asteroids with his telescope 250 miles northwest of Sydney, Australia, discovered the approaching rock last week.

"It's not something to worry about, but something to be aware of," he said.

While a direct hit on Earth could be a devastating natural disaster, McNaught said keeping track of asteroids can make a hit "potentially preventable."

"If discovered in advance and with enough lead time, there is the possibility of pushing it off course, if you have decades of advance warning," McNaught said. "If you have only a few days, you can evacuate the area of impact, but there's not a great deal [else] you can do."

In either case, he said, a global catastrophe as depicted in Hollywood movies such as "Deep Impact" is "very, very unlikely."

The 2009 DD45 asteroid circles the sun every 18 months, but its path will not threaten this planet at least for the next century, he said.

Zot! Or Not?

Dave Fulghum's post on renewed activity with non-expendable high-power microwave (HPM) weapons reminded me of an offhand comment at a conference in 2006, where a US officer commented that - in the USAF - HPMs and unmanned combat air vehicles (UCAVs) were so intimately linked that in Air Combat Command, they belonged to the same office.

What might be a big clue emerged in one USAF presentation a few years ago, in the form of a single piece of artwork:

'

What it shows makes a lot of sense. An HPM is going to work best pointed straight down. since you don't want to defocus the energy by smearing it along the ground. Also, like radar, HPM likes a large antenna (equals narrow beam), and how better to install one - particularly in a small stealthy platform - than horizontally in the weapon bay, aiming down?

Of course, then you need to overfly the target and get as close as possible (effectiveness diminishes with range) and a very stealthy UCAV is a good way to do that. It also avoids any health hazards to an operator, who'd otherwise be sitting a few feet away from a gigawatt-class microwave source.

By the way, someone who appeared very confident in the results of his studies assured me a few weeks ago - quite categorically - that the US already has UCAVs in service, developed and operated in the black world. So maybe that UCAV/HPM office got something done.

Obama wants to trade anti-missile system for Russian help with Iranian nukes

WASHINGTON, March 2 (Reuters) - U.S President Barack Obama has offered to back off deploying a new missile defense system in Eastern Europe if Russia helps stop Iran from building nuclear weapons, The New York Times reported on Monday.

Obama offered the deal in a letter hand-delivered to Russian President Dmitri Medvedev in Moscow last month by top administration officials, the newspaper reported, citing U.S. officials it did not identify.

A senior U.S. official confirmed to Reuters that Obama had sent a letter on the subject to his Russian counterpart.

"We can confirm that President Obama sent a letter to President Medvedev," the senior U.S. official said.

"The letter touched on a range of subjects, including missile defense and how it relates to the Iranian threat."

Russia vehemently opposes the deployment of a U.S. missile defense system in Poland and the Czech Republic. The system was proposed by the administration of former President George W. Bush.

Moscow has not yet responded to Obama's offer, the report said.
