    Brazil postpones decisions again for its new corvettes

    Victor Barreira, Istanbul - IHS Jane's Defence Weekly The Brazilian Navy has postponed by about two months the short list and best and final offer (BAFO) decisions for its ambitious Tamandaré-class corvette project, the second leading priority within the force. The newly established schedule calls for the short list and BAFO announcements to occur in October and December respectively, the navy told Jane's on 17 August. The navy said it is delaying its decision because it needs additional information from the competitors to properly analyse the bids. Service officials provided no additional details on what information it still requires. The navy has not said how many companies will be included on the short list.

  • European States Plan For Hypersonic Defense

    European States Plan For Hypersonic Defense

    Tony Osborne The complex nature of intercepting hypersonic weapons may predicate air-breathing propulsion technologies to provide additional range, speed and energy. European countries have linked arms to develop a counter to the emerging threat of hypersonic weapons and enhance their ballistic missile defense (BMD) capabilities. The Timely Warning and Interception with Space-based TheatER surveillance (Twister) project, led by France and supported by Finland, Italy, the Netherlands and Spain, is one of 13 new multinational programs that were given the backing of the EU's Permanent Structured Cooperation (PESCO) initiative in November. It says it aims to develop a European system that can “detect, track and counter” more complex missile threats and give member nations a “self-standing ability to contribute to NATO's ballistic missile defense.” Currently, only a handful of European nations can counter ballistic missiles, including European users of the Raytheon Patriot (Germany, Greece, the Netherlands and Spain), as well as France and Italy with the Eurosam SAMP/T. But none of those systems is ready to deal with the new generation of threats emerging from Russia and China, including hypersonic gliders, hypersonic and high-supersonic cruise missiles, and maneuverable next-generation combat aircraft. The U.S. has also begun examining technologies through its Regional Glide-Phase Weapon System (RGPWS), disclosed by Aviation Week in December, and the Hypersonic Defense Weapon System. “We have seen the hypersonic threat coming,” says Rainer Stockhammer, team leader for Twister at European missile manufacturer MBDA. “Over the last five years we have performed studies into these new threats, which are new in terms of both novelty and maneuverability, and now we are in a position to answer this PESCO call.” MBDA is now positioning itself for a role in developing the endoatmospheric interceptor that could be the backbone of the wider Twister system in the 2030s, describing the future system as “disruptive” and “technologically demanding.” The company will not discuss what architecture it is studying for the future interceptor, but Stockhammer says MBDA's experience with the Aster family of vertically launched surface-to-air missiles and the Meteor air-breathing, beyond-visual-range air-to-air missile has given it a “good position . . . to be able to develop a solution.” The company's artist's impression depicts a missile clearly equipped with air intakes, which would suggest the use of a ramjet like on the Meteor. Use of a ramjet would provide not only more range and speed, but also more energy in the final stages of an engagement to maneuver against hypersonic gliders and other maneuverable reentry vehicles. “We know what kind of accuracy and range we need from the sensing part,” says Stockhammer. “Now we will look at a way to manage the unpredictability and look at engagement planning. . . . This is where we are investing.” MBDA has also been looking at the command-and-control mechanisms required for such a system and how it would interface with existing and future sensors. Individual governments will ultimately decide how they will equip with the future interceptor, but MBDA expects it to arm ships and a ground-based air defense system, with the expectation the system may have to squeeze into existing launch boxes and vertical launch tubes on surface ships. Securing the nod from PESCO is a major step forward for the program. The next step will be for the five nations to begin hammering out a concept and a high-level requirement. MBDA officials say they are working toward a timeline of the 2030s to produce an operational system. By working through PESCO, the five nations are hoping this will enable them to secure development funding from the European Defense Fund (EDF), which is expected to provide €13 billion ($15 billion) to support collaborative defense projects in 2021-27. It is unclear how much a program such as Twister could receive from the fund. Money will also be provided by national governments involved in the Twister program. Although MBDA lobbied in France for European nations to pursue an evolution of European BMD capabilities, prompting Paris to take a lead in what became Twister, the company is unlikely to be the only player in the program. The interceptor will be just one component of Twister. The PESCO initiative also calls for space-based early warning, but no details have emerged about the European industry approach to this yet. PESCO and EDF rules call for cooperation between industry, particularly small and medium-size enterprises, as well as between member states. “We would need to build an industry consortium that is clear, but it is too early to talk about how this might look,” notes Stockhammer. The PESCO initiatives allow for additional nations to join and observe the programs, although it remains unclear whether the EU will allow so-called third countries, which will include the UK after Brexit, to participate in such projects. Denmark, Malta and the UK remain outside of PESCO. Twister is the second missile initiative pursued by PESCO. The other is for a beyond-line-of-sight development of MBDA's MMP man-portable guided missile, a program proposed by France and supported by Belgium and Cyprus. https://aviationweek.com/defense-space/european-states-plan-hypersonic-defense

    Israel increases training via virtual battlefield center amid Hezbollah tensions

    By: Seth J. Frantzman Israeli Defense Forces have completed several exercises with a new Brigade and Battlegroup Mission Training Center. Tensions with Hezbollah in Lebanon have grown this month and the IDF officials say they face a constant threat of attacks and need to be prepared to respond. Virtual exercises enable a brigade's officers to train while not taking away resources from the field. The center is also part of a growing digitization effort to give more tools to the IDF during its multi-year Momentum plan that includes new networked technology. Lt. Col. Netanel Shamaka, commander of the Special Forces battalion of the Givati brigade, said the latest exercise used this new virtual combat system and it “enabled us to get an in-depth understanding of battlefield scenarios.” Two brigades have gone through the training in June and July, and up to eight more will go through by the end of the year. “The IDF's ability to improve and develop creates an atmosphere of initiative and innovation among the various combat ranks - which improves combat capability. The Givati Brigade is the first brigade to begin training in this way,” Shamaka said. Training took place at the Training Command Headquarters at the Julis base near Ashkelon. The B2MTC was developed by Elbit Systems. Upgraded twice with new capabilities, databases and after-action reports, the virtual simulator provides better coordination on the battlefield, according to Tal Cohen, senior director of land training and simulation at Elbit Systems. Virtual training centers, like the one the IDF uses, have been increasingly popular worldwide. Elbit points to its work with the Royal Netherland Army simulation center (SimCen). “Military operations are becoming increasingly complex, while large-scale exercise opportunities occur less frequently due to cost, logistics and environmental constraints. Elbit Systems' new trainer provides Armed Forces with a flexible and scalable solution to train commanders,” according to Elbit Systems. The Givati brigade is usually deployed in southern Israel opposite the Gaza frontier. “The training prepared us for battle from a different angle. we will implement this on the battlefield on the day of command,” Shamaka said. Israel has faced tensions with Hamas in Gaza over the last years, including more than 1,500 rockets fired and clashes along the border, incidents at sea and involving drones. In addition, on July 23 Israel boosted ground forces along the Lebanese border over concerns about escalation with Hezbollah. Israel is also involved in a multi-year campaign to confront Iranian elements in Syria and around the region. This complex battlefield, using 5th generation F-35s and the latest air defense, with more concentration on special forces is suited to virtual training because modern commanders have more technology at their fingertips and face larger challenges dealing with systems that involve artificial intelligence and algorithms to aid in battle management. During the recent training soldiers experienced fighting in simulated urban terrain fortified by Hezbollah. The simulators are divided along the lines of a brigade, with command rooms and platoon leaders and company commanders and exercises continuing for several days. Replicas of Lebanese villages appear on screens with the threatsthat the soldiers would encounter, such as Hezbollah bunkers. The system documents failures in the field and virtual casualties inflicted to help units learn from mistakes. Because the IDF's Momentum plan foresees bringing as many capabilities to the front as quickly as possible during a conflict, this digital battlefield aids in improving coordination. It is supposed to close gaps between battalion and company levels as well without eliminating traditional field exercises. Cohen says recent upgrades mean the simulator gives more than 100 officers from company to brigade level access to peripheral units, logistics, UAVs, helicopters, artillery, aircraft and all the other combined arms and elements that may be present on the battlefield. That means that pilots have the opportunity to sit in the same room on the virtual trainer behind a screen and then meet with their company commander counterparts for after action discussions that wouldn't necessarily take place in a field exercise. With Hezbollah tensions overshadowing training this July, the virtual exercise mimicked real-world challenges. “The virtual exercise was designed and generated to take place on the Lebanese border, in the Northern region of Israel. Facing the constant threat of attacks from Hezbollah, the IDF needs to be prepared to respond accordingly,” Shamaka said. “Should there be a need to destroy Hezbollah's infrastructure in Lebanon, we must be able to maneuver in a populated and complex environment. This virtual simulation system provides personnel with experience and familiarizes them with the hostile environment they would need to face in the case of conflict.” In the past Israel faced challenges in the 2006 war because of communications problems between units and dealing with Hezbollah fighters dug-in to the rural terrain and rocket fire near villages. Maj. Gen. Yoel Strick, ground forces commander of the IDF since 2019 and a key part of the Momentum multi-year changes, has been pushing for increased use of the virtual simulators, Cohen said. Elbit expects an expansion of training next year. https://www.defensenews.com/global/europe/2020/07/27/israel-increases-training-via-virtual-battlefield-center-amid-hezbollah-tensions
