UAVs for Arctic surveillance?

Further to this post and this one (see ends of posts), this makes sense:
Remote-controlled aircraft will patrol Arctic: military
It seems to me that we are likely to buy one aircraft for Army support (not the Predator) and another for Arctic--and I would presume general maritime--surveillance. Surely the Global Hawk would be best suited for the latter role in terms of range and endurance?

Meanwhile, Steve Janke (with the Arrow in mind) muses over building our own UAVs. I don't see the problem he does with US-sourced aircraft--after all any replacement for the Aurora is likely to be from the US (unless we give up on long-range manned maritime surveillance completely).

In any event we've been there before with UAVs.

Boeing, AFRL show UAVs can perform automated aerial refueling

Can an unmanned aerial vehicle be made smart enough to autonomously rendezvous with a tanker aircraft and refuel? Based on recently concluded flight tests by the U.S. Air Force Research Laboratory and Phantom Works, it can.

"By adding an automated aerial refueling capability to UAVs, we can significantly increase their combat radius and mission times while reducing their forward staging needs and response times," said David Riley, Phantom Works program manager for the Automated Aerial Refueling program.

The goal of the government–industry AAR program is to develop and demonstrate systems that will enable UAVs to safely approach and maneuver around tanker aircraft so they can successfully perform boom and receptacle refueling operations. The systems -- including a flight control computer and control laws developed by Phantom Works -- are demonstrated using a Calspan Learjet specially equipped to fly autonomously as a UAV.

During flight testing on Sept. 12, the AAR system autonomously guided the autonomous Learjet up to a Boeing KC-135R tanker and successfully maneuvered it among seven air refueling positions behind the tanker -- contact, pre-contact, left and right inboard observation, left and right outboard observation, and break away. The system controlled the Learjet for more than 1 hour and 40 minutes and held the aircraft in the critical contact position for more than 19 minutes.

A pilot flies the Learjet to and from the vicinity of the tanker and stands by to take over if necessary, but does not otherwise control the aircraft during the refueling maneuvering portion of the experiment.

"These tests show that we are making great advancements in system integrity, continuity and availability through improved relative navigation algorithms, control laws and hardware," Riley said. "They also show we are making great strides toward transitioning AAR technology into production."

Plans call for a follow-on Phase II program that will include autonomous multiship operations and delivery of fuel to the surrogate UAV.

The AAR team is made up of a diverse set of government and contractor organizations. The U.S. government team includes:

The Air Vehicles, Sensors, Human Effectiveness and Information Directorates at the Air Force Research Laboratory The Air Force Flight Test Center and Air Force Test Pilot School at Edwards Air Force Base, Calif. Naval Air Systems Command (NAVAIR) The 107th Air Refueling Wing, 827th Aircraft Sustainment Group, at Tinker Air Force Base, Okla. The Defense Advanced Research Projects Agency Information Exploitation Office The Aeronautical Systems Center Air Mobility Command. The AAR industry team includes:

Boeing Phantom Works, which built the AAR flight control computer and developed the AAR control laws Calspan, which operates the Learjet Rockwell Collins, which supports KC-135 operations and builds the Tactical Targeting Network Technologies data link L3 Communications, SySense and the Illinois Institute of Technology, which work with NAVAIR to develop the precision Global Positioning System-based relative navigation system Northrop Grumman, which built the GPS receivers and developed an Electro-optical/Infrared position sensing system General Dynamics Advanced Information Systems, which provides systems engineering and flight test management assistance Syngenics, which coordinates the AAR trade studies Bihrle Applied Research, which integrates simulation environments The Institute for Scientific Research, which develops image processing algorithms Coherent Solutions, which develops Required Navigation Performance.

Here's a question, persuant to the post about the Bears etc.

Here's my scenario: the UAVs pick up the presence of the Bears on a training mission or (FSM forbid) a real attack, how long are response time are we talking with something offensive?

Interlocking with that, I know that the Predator has been fitted with Hellfires for ground targets, does anyone know if anything is in production now that can engage air targets?

for the most part, UAV's are ground oriented and "probably" wouldn't pick up the incoming airborne Bears.

We still maintain long range search radars at some ex DEW line sites that keep watch over the pole ( the radars are remote sat linked to operators in the south - in the hole at North Bay)

We we get plots from other NATO members and the US so the Bears are known about a long time before they get near.


To the best of my knowledge no UAV's have A2A missiles, although I'm sure it could be done
