  Comparative SWOT & Program Strategy Assessment of the World's Top 6 Western Combat Aircraft (4/4.5 Gen) Programs - Boeing, Lockheed Martin, Dassault, Eurofighter and SAAB - ResearchAndMarkets.com

  Combat jets have formed the core of the force structure of Air Forces globally since their advent in the piston engine powered form on to the battlefields during the World War I with technological evolution having heralded the age of jet powered combat aircrafts by the end of World War II with the usage of turbojet powered combat aircrafts by both sides towards the later part of the war. The radical shift in the prevailing, traditional rule based world order with the rapid build-up of military capabilities by China and resurgence of Russia on the world horizon having already propped up defense spending across most regions & parts of the world. Additionally, ongoing conflicts & unrest across some parts of the world, especially, the Middle East has also led to a spurt in defense spending over the recent years driving demand for western origin military hardware by most nations. The global defense spending reached the $1.9 trillion level for 2019, growing by over 3% year on year to reach its highest level since the Cold war era, accounting for around 2.2% of the world GDP for 2019. Fighter jets have remained a core focus area for nations around the world with their significant role & capabilities in aerial combat, interdiction, penetration of enemy air defenses, ground attack and air dominance/superiority roles. The 21st century has marked the mainstream shift towards the 5th generation aircrafts with the U.S. maintaining the lead as always, with its F-22 Raptor program in late 1990s and with the F-35 Lightning II in the 21st century, while similar 5th generation programs are being developed and produced by Russia, China & South Korea. The quest towards the development of 6th generation aircrafts, poised to enter service in the 2030s, has also begun, led by the European FCAS & the British Tempest programs. This report, however, focuses on the key fighter jet program from the perspective of competition for pursuit of international exports opportunities, which has mostly been led by 4 or 4.5 generation aircrafts so far with the same mostly aimed at capabilities expansion or fleet replacement. The study, thus, takes a close look at the Top 6 4/4.5 generation fighter jet programs currently in production from the international markets perspective with focus on comparative assessment of respective programs along with a comparative SWOT analysis on these programs which have on multiple occasions have come to face off each other in multiple international competitions over the recent years. The report provides a comprehensive, comparative analysis of the Strengths & Weaknesses of these combat jet programs relative to each other while scanning out environmental opportunities & threats for these in a rapidly evolving post COVID-19 world scenario (which is likely to see pressures on defense spending across most parts of the world over near term) which further enhances the relevance & usefulness of this report. https://www.businesswire.com/news/home/20200527005384/en/Comparative-SWOT-Program-Strategy-Assessment-Worlds-Top

  Here’s what the Army wants in future radios

  By: Mark Pomerleau Advancements in electronics and tactics by high-end adversaries are forcing the Army to change the way it revamps and optimizes its communications network against current and future threats. The problem: adversaries have become more proficient and precise in the sensing and jamming of signals. “What we're looking for in terms of resilience in the future is not only making individual links more anti-jam and resilient, resistant to threats, but also having the ability to use multiple paths if one goes down,” Joe Welch, chief engineer at Program Executive Office Command, Control, Communications Tactical (C3T), told reporters during a network demo at Fort Myer in early March. “Your phones work this way between 4G and Wi-Fi and that's seamless to you. That's kind of the target of what we're intending to provide with next-generation transport for the Army's tactical network.” Members of industry are now looking to develop radios to these specifications outlined by the Army. “We have an extensive library of waveforms — 51, 52 waveforms that we can bring to bear — that we can say look we can use this waveform to give you more resilience with this capability,” Jeff Kroon, director of product management at Harris, told C4ISRNET during an interview at the AUSA Global Force Symposium in Huntsville, Alabama, in March. “Down the road, we need to talk about resilience and what's going on with the near-peer threats.” Next-generation systems, leaders believe, will be able to provide this necessary flexibility. “The radios that we're looking at buying now — the manpack and the two-channel leader radios — have shown themselves to be able to run a pretty wide range of waveforms and we think it postures us to run some changes to those waveforms in the future as we look at even more advanced waveforms,” Maj. Gen. David Bassett, program executive officer of C3T, told reporters at Fort Myer. While jammers have become more powerful and targeted in recent years, officials contend the entire spectrum can't be interrupted at once. The Army realizes links won't be jam-proof, Bassett told reporters at Fort Myer, so it is looking at how they can be either more jam-resistant or able to switch seamlessly across portions of the spectrum that are not being jammed. Kroon noted that one of the big developments within the radio community down the road will be radios that seamlessly switch frequencies or waveforms without direct user input. “I think, as we move forward, we'll start to have more cognitive capabilities that will allow [the radio] to adapt automatically, and keep the user focused on their own job and let the radio handle the rest,” he said. In addition to multiwaveform and a large range of spectrum coverage, Kroon said the Army is also really looking for multifunction capabilities within radios. Radios also have to have passive sensing capabilities to be able to understand the signals in the environment and provide some level of situational awareness of the spectrum environment. “They have to have visibility into what's going on around them ... not just for [electronic warfare] purposes but sometime just knowing what's going on in the spectrum around you as a planner is really important,” Kroon said. “What's actually going on out there, I don't know I was told this frequency was clear, how do I really know. Having a radio come back and say look what we hit ... it is actually very useful.” https://www.c4isrnet.com/show-reporter/global-force-symposium/2018/04/06/heres-what-the-army-wants-in-future-radios/

  F-35 program finishes years-late tests needed for full production

  The complex simulations at Naval Air Station Patuxent River in Maryland were meant to test how well the F-35 would perform in real-world combat scenarios.
