The Swedes who build the Gripen fighter are known for being practical, producing advanced fighters that are relatively cheap (at least compared to almost everyone else). At the Paris Air Show the Gripen folks, SaaB Group. very deliberately floated an interesting idea. Since the Gripen uses fly-by-wire technology and advanced avionics which virtually eliminate the need… Keep reading →
May’s been a good month for Navy drones and Northrop Grumman. First Northrop’s X-47B, forerunner for a future generation of unmanned reconnaissance and strike planes, made its first launch and first touch-and-go landing on an aircraft carrier. Today, Northrop’s land-based MQ-4C Triton drone made its first flight, out of the company’s facility in Palmdale, California:… Keep reading →
Adm. Jonathan Greenert is Chief of Naval Operations, the Navy’s most senior officer. Greenert has emphasized the convergence between traditional electronic warfare — long a strong suit of the Navy — and the new arena of cyberspace. In this op-ed written for Breaking Defense, the admiral argues that “cyberspace and the electromagnetic spectrum” must be viewed as a single domain of warfare on par with land, sea, air, and space. Click here to read more from Greenert’s chief cyber aide, Rear Adm. William Leigher. — The Editors.
An unmanned aircraft is returning to its ship when it suddenly loses control, plummeting 5,000 feet to the water and shattering on contact with the surface. Halfway around the world, the lighting at an airfield in North America flickers several times before finally going dark, forcing airliners to seek out an alternate airport to land. In a windowless control room, system administrators at a large international corporation are alerted to higher than normal internet traffic on their servers: Before they can intervene, files which hold the key to a new cancer-fighting drug are exfiltrated via the company’s wireless network, placing 10 years of research and more than a billion dollars of investment at risk. These kinds of events, although uncommon, do happen – and they arise from our dependence on the electromagnetic (EM) spectrum.
The electromagnetic spectrum is an essential – and invisible – part of modern life. We unlock our car and control our television with remote controls, routinely communicate using smart phones, and avoid automobile or aircraft collisions with any number of electronic sensors. EM transmissions and cyberspace are also essential to modern warfare. Our military forces use wireless computer networks to coordinate operations and order supplies, use radars and sensors to locate each other and the enemy, and use electronic jammers to blind enemy radars or disrupt their communications.
With wireless routers or satellites part of almost every computer network, cyberspace and the EM spectrum now form one continuous environment. This environment is so fundamental to naval operations, and so critical to our national interests, that we must treat it on par with our traditional domains of land, sea, air, and space. In fact, future conflicts will not be won simply by using the EM spectrum and cyberspace, they will be won within the EM spectrum and cyberspace. This will require changes to our operating concepts, military systems and – most importantly – a new way of thinking in our Navy.
From primitive tool to double-edged sword
Our use of the electromagnetic spectrum has changed dramatically since Heinrich Hertz discovered it in 1888. Right away, EM transmissions were used to communicate with ships at sea. But in 1922, Naval Research Laboratory scientists also used radio waves to detect a moving ship, creating radio detection and ranging, or radar. With war raging in Europe and East Asia, in 1939 the new technology was sent to USS New York for testing and experimentation. Based on the successful results, radars were soon installed throughout the fleet and became pivotal to winning the war at sea.
Since World War II, the military pioneered new uses for the EM spectrum, from satellite navigation and radar jammers to short-range wireless networks and infrared missile seekers. Now computer processors and transmitters are inherent in almost all our shipboard equipment, and even mechanical systems such as gas turbine engines and guns are “on the grid.”
The EM spectrum is also an integral part of our military and civilian computer networks. Just like in our homes or in a Starbucks, a wireless network provides mobility. We can keep far-flung forces, aircraft and ships connected with each other and commanders back home, but wireless systems also provide ways to access a network that is otherwise isolated from the wider internet. Navy forces have a unique opportunity to exploit (or be exploited by) this access because of their presence around the world and ability to closely approach opponents via the sea.
Commanding the electromagnetic and cyber environment
America’s key military advantage for the last twenty years has been our ability to sense and create a picture of our surroundings, then use that picture to control the air, sea, and undersea domains. The systems that build our operational picture have performed well in the relatively unchallenged EM environments of Iraq and Afghanistan, but in future conflicts that will not be the case.
Inexpensive jammers, signal detectors, computer processors and radios make it easier for unfriendly states, terrorists, and criminals to manage their efforts while jamming our own ability to sense and communicate. Meanwhile, the number of users in the EM spectrum has grown dramatically over the last two decades. The result is an environment we struggle to sense, understand and use in warfare. We need a concerted effort to harness the EM and cyber environment to give us a warfighting edge.
First, we will improve our awareness of the EM and cyber environments. We will detect and assess in real time what is happening in the EM and cyber environment, predict how the environment will react and use this knowledge to guide our own actions. Building this level of awareness will be challenging. Our tools for collecting and analyzing information in the EM and cyber environment are limited, and we lack the familiarity and understanding to take full advantage of the information we do have. To build better tools for sensing the EM and cyber environment, we will work closely with industry and academic researchers.
Second, we will employ agility in the EM spectrum and cyberspace. This will reduce our vulnerability to detection and maximize our ability to defeat jamming and deception. If our systems can shift frequency over a wide range, use shorter “burst” transmissions, employ small directional beams, or move applications between servers automatically in response to a sensed anomaly, our EM and cyber operations would be less predictable, harder to classify, and more difficult to counter or disrupt. One example of this is our “Integrated Topside” project, which uses modular, reconfigurable antennas in a ship’s superstructure that can be alternatively employed as radars, listening devices, or radios.
Finally, we will change how we view the role of EM and cyber in warfare. EM and cyber systems and operators won’t just support air, land, and space operations as they did in previous conflicts. Aircraft and ships will instead help get our EM and cyber capabilities into the fight. This will require developing the same “real-time” flexibility in planning and executing EM and cyber operations as we have today in the traditional “physical” domains.
Warfare in the EM spectrum and cyberspace is much more challenging than in other domains such as undersea or in the open ocean. The web and spectrum are crowded with civilian and commercial users who are rapidly developing and fielding new technologies. To take the high ground in this new environment, we will have to work with industry and fundamentally change our approach to operations and warfare. Most importantly, we will leverage those strengths that are impossible to reverse-engineer: the expertise and flexibility of our research base, our history of adaptation, and the skill and perseverance of our Sailors.
CAPITOL HILL: If there’s one command — a very important one — that must worry about the short term impact of sequestration, it’s Strategic Command, those who command three of the most important weapon systems we deploy — nuclear weapons, cyber and space. Roughly 60 percent of STRATCOM’s headquarters staff do not wear uniforms. And, as anyone knows who’s been following the debacle we call sequestration, one of the first and hardest human impacts will be furloughs, as involuntary layoffs for federal employees are known.
Gen. Robert Kehler, STRATCOM’s leader, told the House Armed Services Committee today in his written testimony that he is, “extremely concerned about the impacts of actual and potential budget reductions on our people. While I believe these amazing professionals will continue to cope with uncertainty in the near-term, I cannot say the same over time if the financial risks to the individuals and their families persist.”
I covered STRATCOM for five years while at Space News and was always struck by how pervasive the civilians were. Keep Reading →
WASHINGTON: This Saturday the Navy will christen its newest nuclear-powered submarine, the $2.6 billion USS Minnesota at the Newport News shipyard in Virginia. Countless movies have cemented the popular image of subs as stealthy underwater killers, stalking hapless surface vessels with periscope and torpedo. But today’s Navy is experimenting with launching robotic mini-subs and even unmanned aerial vehicles (UAVs) from Virginia-class attack subs like the Minnesota.
In Navy tests of a mini-UAV called Switchblade, “you can launch it, you can control it, you can get video feed back to the submarine,” said Rear Adm. Barry Bruner, chief of the undersea warfare section (N97) on the Navy staff, at the recent Naval Submarine League symposium in suburban Washington. Future subs could also launch unmanned underwater vehicles (UUVs) to scout ahead stealthily beneath the surface. “It sure beats the heck out of looking out of a periscope at a range of maybe 10,000 to 15,000 yards on a good day,” Bruner said. “Now you’re talking 20 to 40 miles.” Keep reading →
The Navy’s jet-powered P-8 Poseidon patrol plane boasts plenty of advances over the P-3 Orion turboprops it will replace, but for the sensor operators the favorite feature will be very basic: They won’t throw up as much.
The P-3′s notoriously rough ride at low altitudes and the gunpowder-like stench from the launch tube shooting sonar buoys out the back meant that, “typically, every mission or two you’d have somebody get sick [and] start throwing up into their air sickness bag,” said Navy Captain Aaron Rondeau, a P-3 veteran who now runs the P-8 program. “We haven’t seen that much with the P-8.” Keep reading →
The Joint Staff looked at the last decade of operations in a report, “Enduring Lessons from the Past Decade of Operations,” that hit cyberspace this summer. I applaud the Joint Staff effort to assemble lessons from operations over the past decade. What will be key is for people to actually learn them.
There is much value in several sections of the report. In particular, creating an integrated and interdependent strategy for intelligence gathering; taking a “whole of government approach;” the importance of perception management as an element of security operations; and ways to better integrate coalition operations.

NAVAL AIR STATION PATUXENT RIVER, MARYLAND: Most drones land the same way manned airplanes do, on a runway. But what if you don’t have a runway? Well, with an unmanned aerial vehicle called the RQ-21, Marines can string up a cable and snag the drone out of the sky.
The military and unmanned aerial vehicle maker Insitu, a subsidiary of Boeing, pioneered the “skyhook” technique with a small drone called Scan Eagle that has seen wide service in Afghanistan and Iraq. But now they’re scaling that technology up with the larger and more capable Insitu Integrator, being developed for the Marines and Navy under the designation RQ-21A. Scan Eagle weighs 44 pounds, about as much as the average four-year-old boy; Integrator weighs 135 lbs, as much as a 14-year-old. That 300 percent increase in weight is literally a stretch for the crane-and-cable mechanism that snatches the drone out of the air in mid-flight. Keep reading →
ARLINGTON, VA: At $2.6 million, the contract award that Lockheed Martin will announce today to upgrade something called the Distributed Common Ground System is a rounding error in the aerospace giant’s $46.5 billion annual revenue. But in an age of austerity, when mega-programs like Lockheed’s flagship Joint Strike Fighter are under ever-increasing scrutiny, small can be beautiful. The DCGS approach — modest, incremental, and based on free open-source software — is an interesting model for a difficult era.
DCGS does what’s called “fusion,” combining “intelligence, surveillance, and reconnaissance” (ISR) data from different kinds of drones and manned aircraft into a single coherent picture for analysts on the ground. The different services all have their different variants, with something called the DCGS Integrated Backbone (DIB) supposed to connect them. That’s the kind of complex IT integration challenge that has bedeviled programs like the Joint Tactical Radio System (JTRS) and the Army’s Future Combat System (FCS) — for which Lockheed also did fusion work before its cancellation in 2009 — and at one point DIB seemed headed down that same, well-trodden road to nowhere.
