In the face of a rising near-peer threat to electronic communications, the Air Force is pressing forward with efforts to develop a new, more resilient, harder-to-jam waveform that soldiers could use on the battlefield.
The service expects to receive responses from industry soon on a recent request for information around protected satellite communications. The request sought industry guidance on how best to implement a new, more resilient protected tactical waveform (PTW), which enables anti-jamming capabilities within protected tactical SATCOM.
“The Air Force is looking to protect our warfighter's satellite communications against adversarial electronic jamming,” the Air Force's Space and Missile Systems Center (SMC) said in a written statement to C4ISRNet.
The threat comes from “adversarial electronic jammers that are intended to disrupt and interfere with U.S. satellite communications,” leaders at SMC said. Protected tactical SATCOM is envisioned to provide worldwide, anti-jam communications to tactical warfighters in benign and contested environments.
The quest to solidify satellite communication links has taken on increasing urgency in recent years. As satellite communications has emerged as an integral component in the military's command and control infrastructure, potential adversaries have stepped up their ability to disrupt such links.
“Tactical satellite communications are vital to worldwide military operations,” the agency noted. “Our adversaries know this and desire to disrupt U.S. satellite communications. The Air Force is fielding Protected Tactical SATCOM capabilities to ... ensure warfighters around the globe have access to secure and reliable communications.”
Industry is expected to play a key role in the development and deployment of any new waveform. Officials at SMC said that early prototyping efforts will be conducted through the Space Enterprise Consortium (SpEC), which is managed by Advanced Technology International. SpEC acts as a vehicle to facilitate federally-funded space-related prototype projects with an eye toward increasing flexibility, decreasing cost and shortening the development lifecycle. The organization claims 16 prototype awards to date, with some $26 million in funding awarded.
Understanding the protected tactical waveform
Government documents describe PTW as the centerpiece of the broader protected tactical SATCOM effort, noting that it provides “cost-effective, protected communications over both military and commercial satellites in multiple frequency bands as well as broader protection, more resiliency, more throughput and more efficient utilization of satellite bandwidth.”
A flight test last year at Hansom Air Force Base suggested the emerging tool may soon be ready to deliver on such promises.
While SMC leads the PTW effort, Hanscom is working in collaboration with MIT Lincoln Laboratory and the MITRE Corp. to conduct ground and airborne terminal work.
Researchers from MIT's Lincoln Laboratory flew a Boeing 707 test aircraft for two and a half hours in order to use the waveform in flight. With a commercial satellite, officials gathered data on the PTW's ability to operate under realistic flight conditions. “We know this capability is something that would help our warfighters tremendously, as it will not only provide anti-jam communications, but also a low probability of detection and intercept,” Bill Lyons, Advanced Development program manager and PTW lead at Hanscom, said in an Air Force news release.
The test scenario called for the waveform to perform in an aircraft-mounted terminal. Evaluators were looking to see whether its systems and algorithms would function as expected in a highly mobile environment.
“Everything worked and we got the objectives accomplished successfully,” Ken Hetling, Advanced Satcom Systems and Operations associate group leader at Lincoln Laboratory, said in an Air Force press release. “The waveform worked.”
Asking for industry input should help the service to chart its next steps in the development of more protections. While the request does not specify when or how the Air Force intends to move forward, it is clearly a matter not of whetherthe military will go down this road, but rather when and how.

BY JOSEPH TREVITHICK German officials have reportedly asked their American counterparts about whether it would be possible to turn the Eurofighter Typhoon into a nuclear strike aircraft. The answer to this question could have serious ramifications on Germany's effort to replace its aging Panavia Tornado combat jets, which are certified to carry U.S. B61 nuclear bombs during a crisis as part of an inter-NATO agreement, and reinforces previous reports that the European fighter jet is the German Air Force's preferred option. In April 2018, the German Federal Ministry of Defense sent a formal letter to U.S. officials asking about whether it would be feasible to configure Typhoons for the nuclear mission, how expensive it would be, and how long the process might take, according to Reuters. The German Air Force's ability to fly nuclear strikes has become an increasingly important issue even though the country is not a nuclear power itself. During the Cold War, Germany, as well as other NATO allies, agreed to host American nuclear bombs with the understanding that their aircraft could be called upon to employ them if a major conflict with the Soviet Union broke out. After the Cold War, this arrangement has persisted and the Germans continue to keep an unspecified number of B61 bombs at Büchel Air Base near the borders with Belgium and Luxembourg. The problem is that the only German aircraft that can carry these weapons are the Tornados, which are in desperate need of replacement. Availability rates for the Cold War-era swing wing jets have dramatically dropped in recent years. In 2015, state broadcaster Deutsche Welle reported that only 30 of the approximately 85 remaining aircraft were airworthy at any one time. The aircraft also lack cockpits that will work with night vision goggles, which limits the jet's ability to perform missions at night. In March 2018, German magazine Der Spiegel also obtained a report calling into question the security of the Tornado's data links. “This could in the worst case mean that the demand for an encrypted communication system for the Tornado weapons system can't be achieved,” the document stated according to the report. “That means the Tornado weapons system may not take part in NATO missions.” The German Air Force disputed the story, saying that all of the Tornados set aside to support the alliance's requirements had the equipment necessary to perform their missions. Regardless, the service has made no effort to hide the importance of replacing the jets. The Germans will need to certify whatever aircraft replaces the Tornado as a nuclear-capable platform in order to continue performing the mission. In addition to Eurofighter, the Germans are considering an unspecified variant of Boeing's F-15 Eagle or that company's F/A-18E/F Super Hornet, and Lockheed Martin's stealthy F-35 Joint Strike Fighter. The process to make sure any of those planes could carry the B61 would likely include ensuring they could safely drop the bombs at all, as well as developing appropriate mission systems and software to enable this capability under various different attack parameters. In addition, engineers would have to find ways to install the necessary systems and linkages so that the pilot can arm the weapon in flight. Each one of the bombs has a so-called “Permissive Action Link,” or PAL, that prevents the warhead from functioning until an individual puts in a specific code. You can read more about these safety features and other components of the bombs in this past feature. The U.S. military has not certified any variants of the Joint Strike Fighter to carry the B61, but Air Force is in the process of doing so with regards to the F-35A. The aircraft types that Boeing is offering are the only ones in the running that have already gone through this process. But the German Air Force's top preference is reportedly the Eurofighter. Germany already has nearly 130 of the jets in service and recently began adding a robust air-to-ground capability to some of them. “A possible purchase of the Eurofighter would ensure the retention of military aircraft expertise in Germany and Europe, and value creation in our own country,” Germany's Deputy Defense Minister Ralf Brauksiepe told the Green Party's Tobias Lindner in a letter earlier in 2018, according to Reuters. “The weapons system has already been introduced to the Bundeswehr [the German Armed Forces] and is being successfully used.” Replacing the Tornados with Eurofighters does make good sense, something we at The War Zone have noted in the past. As I wrote in December 2017: “Eurofighter, a consortium that includes portions of Airbus Defense in Germany and Spain, BAE Systems in the United Kingdom, and Leonardo in Italy, manage the development and production of the fighter jets. A major sale to the Luftwaffe could be worth billions to the group and help keep the production line running and its employees at work, an important domestic consideration for the Germans. On Dec. 11, 2017, Qatar signed a deal for 24 of its own Eurofighters, making it the ninth country to buy the type. This alone could mean significantly lower training and maintenance costs, not to mention saving on large infrastructure needs, compared to acquiring an entirely new type of aircraft, and especially one with high secondary cost demands like the F-35. It also could make it easier for the Luftwaffe to quickly absorb the new aircraft into its inventory. Existing Typhoon variants are already compatible with the targeting and reconnaissance pods the Luftwaffe uses on the Tornado, as well as many of its weapons. Saab has already tested the Taurus KEPD 350 cruise missile on one of the fourth generation fighter jets, as well, giving it a relatively long-range standoff attack capability." There is a growing concern, however, that the Eurofighter won't be survivable enough to perform the nuclear mission in the future. One source told Reuters that the United States would consider this factor in its response about whether it would certify the jets to carry the B61s. The implication is that the fifth generation F-35 could be the only realistic option. But German authorities reportedly forced the German Air Force's previous head, Lieutenant General Karl Müllner, into retirement over his support for the F-35 option, though it's not clear whether that was over his preference for the jet itself or his public comments on the matter. It is important to note that the United States has been working to make sure the forthcoming improved B61-12 bombs will be compatible with existing NATO platforms, including Tornado, since 2015. Eurofighter, as well as Boeing, also both insist that their aircraft would be able to carry out nuclear strikes in any high-threat environment in cooperation with electronic warfare aircraft and other supporting assets. NATO members regularly train to do just this as part of what is known as Support of Nuclear Operations With Conventional Air Tactics, or SNOWCAT. At the same time, Germany and the rest of the alliance are increasingly worried about Russia's steadily more aggressive foreign policy. This has included veiled and outright threats against member states and non-NATO partners in Europe. Earlier in June 2018, Russian Foreign Ministry spokesperson Maria Zakharova implied that increased U.S. military presence in Norway was an implicit threat toward her country. The Kremlin has also deployed advanced air defenses and other weapons systems, including the S-400 surface-to-air missile system and Iskander nuclear-capable short-range ballistic missiles, along NATO's eastern flanks and within its Kaliningrad enclave on the Baltic Sea. The latter position means that Russian weapons already have the range to engage aircraft flying over Germany proper. Lieutenant General Müllner and other supporters of buying the F-35 had argued that this reality made a stealthy fifth-generation aircraft a necessity. Germany has joined with France to develop a new low-observable combat jetfor both countries. The Joint Strike Fighter program and other stealth fighter development efforts elsewhere make it clear that this process will be long and potentially exorbitantly expensive. There's no guarantee that it will produce a working design any time soon, if at all. For all of its very real issues, the F-35 is in production now. If the German Air Force does decide to replace the Tornados with more Typhoons, it could take up to a decade to certify the latter type for the nuclear mission, according to Reuters. It's not clear when that process might begin, but Germany wants to have all of the older Tornado jets out of service by 2030. This means there is a distinct potential for a gap in capability to occur between when the replacement aircraft arrive and when they're deemed nuclear capable. Domestic and international politics are almost certain to have an impact on the final decision, too. Germany itself is in the midst of a political crisis that traces back the last federal elections in September 2017. A poor showing for Chancellor Angela Merkel's Christian Democratic Union (CDU) part, as well as its allies in the Christian Social Union (CSU), led to six months of deliberations on the future of their bloc. This was the longest the country had been without a government since the end of World War II. Any further upheaval could impact attempts to increase the country's defense spending overall and to address systematic readiness issuesplaguing the German Armed Forces as a whole. Perhaps more importantly, German relations with the United States have plummeted amid a largely personal feud between Merkel and President Donald Trump. Richard Grenell, the new U.S. Ambassador to Germany and a Trump appointee, has suggested he could engage with opposition parties looking to unseat the CDU-CSU alliance. In May 2018, Merkel reiterated comments she had made in 2017 that it was increasingly clear Germany could not rely on the United States for protection. “It's no longer the case that the United States will simply just protect us,” Merkel said in the 2018 speech, which also lauded French President Emmanuel Macron who was on hand to receive an award. “Rather, Europe needs to take its fate into its own hands. That's the task for the future.” This could make the idea of buying any type of American aircraft increasingly politically untenable. It could also potentially raise new questions about whether Germany should be hosting American nuclear weapons in the first place, which is a controversial issue that left-leaning political parties in the country typically oppose on principle. In the meantime, the Tornados are only getting older and are steadily less capable of performing any missions, nuclear or otherwise. As such, Germany and the United States will have to come to some agreement on certifying any future planes soon if the German Air Force intends to continue having a nuclear role at all. http://www.thedrive.com/the-war-zone/21679/the-german-air-force-wants-to-know-if-its-eurofighters-can-carry-u-s-nuclear-bombs

By: Christina Mackenzie   PARIS – French President Emmanuel Macron announced on Dec. 8 that his country's next aircraft-carrier will be nuclear-powered and should be operational by 2038 in time to replace the Charles de Gaulle, which entered active service in 2001. The new aircraft carrier is expected to be the biggest warship France has ever built. Florence Parly, the armed forces minister, said in October that the ship, whatever its propulsion, would be designed to deploy the future combat aircraft system (FCAS) and today her ministry confirmed that the vessel would deploy about 30 of these aircraft “which will be bigger than the Rafales.” The ministry said the ship would be in the 75,000 tonne class (82,673 tons), be around 300 meters long (984 feet) and be able to sail at 27 knots (31 mph), even bigger than the second aircraft carrier that Naval Group was working on in the early 2000s until that program was shelved by the government for lack of money. In comparison, the Charles de Gaulle is 261m (856 feet) long and weighs 42,000 tonnes (46,297 tons) fully loaded. The new ship will have a crew of about 2,000, including the air group. Speaking at Framatome, France's principal nuclear-power company headquartered at Le Creusot in the centre of France, Macron announced just four minutes before the end of his 28 minute speech that he had “decided that the future aircraft-carrier which will serve our country and our navy will, like the Charles de Gaulle, be nuclear-propelled.” It will have two K22 power generators each generating 220 megawatts (hence the 22) derived from the K15 (that generate 150 MW each) that currently power the Charles de Gaulle. Naval Group, which is the prime contractor for these major ship-building projects, immediately issued a statement hailing the decision, pledging to work with its major industrial partners Chantiers de l'Atlantique, TechnicAtome and Dassault Aviation. Pierre Eric Pommellet, chairman and CEO of Naval Group, said, “We are delighted with the announcement (...) which will enable France to maintain its position in the very restricted circle of major powers holding a nuclear aircraft carrier.” Echoing what Macron had said in his speech, Pommellet stressed the importance of projects like this to “ensure the continuity of our skills” and of developing innovative solutions “in the fields of propulsion and high added-value military systems, thus maintaining France's technological lead and its position as a key geostrategic player.” Now that the nuclear option has been chosen to power France's new aircraft carrier, other major decisions will have to be taken, notably concerning the catapults which are a vital part of the project. France has no expertise in this highly specialized technology and so will have to import the catapults from the United States, as it has done for the past 60 years. Those on the Charles de Gaulle are steam-powered, but those on the new aircraft carrier will be electromagnetic. Naval Group and its partners will now start a two-year preliminary design study, which sources said may use a number of the ideas that had been worked on for the aborted second aircraft carrier. That will be followed by more detailed plans with the development phase expected to finish at the end of 2025 at which point the ministry will order the ship. The design phase up to the end of 2025 is expected to cost some €900 million ($1.09 billion) of which €117 million ($142 million) will be spent in 2021. https://www.defensenews.com/global/europe/2020/12/08/macron-kicks-off-french-race-to-build-a-new-nuclear-powered-aircraft-carrier/
