Bulgaria issues request for proposals for fighter jets
SOFIA (Reuters) - Bulgaria has sent a request for proposals (RFP) for 16 new or used fighter jets to replace its aging Soviet-designed MiG-29s to seven countries, the defense ministry told Reuters on Wednesday.
The Black Sea country, which joined NATO in 2004, has called for bids to supply aircraft from the United States, Portugal, Israel, Italy, Germany, France and Sweden.
Last month Bulgaria's parliament approved a plan to buy the jets. It plans to acquire them in two equal stages as part of efforts to improve its compliance with NATO standards.
Some 1.8 billion levs ($1.08 billion) will cover the first eight aircraft, as well as ground handling, team training and three years of initial integrated logistics support.
Potential suppliers include Boeing's F/A-18 Super Hornet, Saab's Gripen, Dassault's Rafale and Lockheed Martin's F-16 or Eurofighter, the ministry said. Sofia is asking manufacturers to provide bids by October 1.
The ministry has called for bids for new or used jets from the United States (F-16 and F/A-18 Super Hornet), France (Dassault Rafale) and Sweden (Gripen C/D) as well as new jets from Germany (Eurofighter 3 Tranche) and used planes from Portugal (F-16), Israel (F-16) and Italy (Eurofighter Tranche 1).
NATO has encouraged its eastern members to develop, buy and operate new alliance equipment.
Some eastern European NATO allies that were once Soviet satellites still rely on Russian-made military jets - two-thirds of Poland's military equipment dates from the pre-1991 Soviet era, for example.
The question of which warplanes to buy has vexed successive governments in Bulgaria for more than a decade.
Sofia aims to raise its annual defense expenditure to 2 percent of the country's gross domestic product by 2024.

RFP Reveals Main Thrust Of U.S. Counter-Hypersonic Plan
Steve Trimble The main thrust of the U.S. Missile Defense Agency's counter-hypersonic strategy has just been revealed. The Regional Glide Phase Weapon System (RGPWS) prototype project demonstrates an interception capability against a medium- or intermediate-range threat. The MDA revealed the existence of the program in a request for prototype proposals released to industry on Dec. 5. An industry day for the RGPWS prototype project is scheduled on Dec. 18 at an MDA facility on Redstone Arsenal, Alabama. The RGPWS shows the MDA is moving faster to field at least a prototype counter-hypersonic capability than previous efforts suggested. The MDA had previously defined a concept for a Hypersonic Defense Weapon System (HDWS). The agency selected 21 proposals from industry in September 2018 for concept definition studies. MDA then down selected to five concepts in late August and early September 2019 for a nine-month-long concept refinement phase. The selected proposals included four kinetic concepts based on existing boosters and one Raytheon-directed energy system. The RGPWS is a parallel effort by MDA to the HDWS. The companies selected for the HDWS concept refinement phase could submit separate proposals for RGPWS. But other companies that were rejected after the concept definition phase or did not participate in HDWS can participate in the RGPWS, says Tom Karako, director of the Missile Defense Project at the Center for Strategic and International Studies (CSIS), who was briefed on the program on Dec. 9. For example, Northrop Grumman's proposal was not down selected for the HDWS concept refinement phase, but it intends to compete for the RGPWS prototype project. “Northrop Grumman is engaged with MDA on Hypersonic Defense Regional Glide Phase Weapon System and will attend the upcoming industry day,” a spokesman says. Northrop has been developing kinetic and non-kinetic options for missile defense, including one concept in the latter category called the Terminal and Regional Electronic Attack Defense System. The acknowledgment of the RGPWS offers a limited glimpse into MDA's development strategy for the burgeoning counter-hypersonic capability. In July 2017, the agency first disclosed plans for funding a hypersonic defense demonstration. An item in the Selected Acquisition Reports for the Ballistic Missile Defense System added $508 million to the program's overall budget to pay for such a demonstration. In March 2019, the agency disclosed it would spend more than $600 million on hypersonic defense capabilities by the end of fiscal 2024. By emphasizing a “glide phase” weapon with a “regional” targeting area, the MDA also provided clues about the intent of the demonstration. It does not appear to be targeting an intercontinental ballistic missile with a nuclear hypersonic glide vehicle as the warhead, such as Russia's Avangard. It is more likely designed to target a hypersonic glide vehicle with regional range, Karako says. Options may include hypersonic glide vehicles on China's DF-17 and DF-21 missiles. “That's a good thing,” Karako says. “It's a smart move for MDA to start there.” Separately, the Defense Advanced Research Projects Agency continues to pursue the Glide Breaker program. It was revealed in July 2018 as a program with a particular interest in “component technologies that radically reduce risk for development and integration of an operational hard-kill system,” according to a DARPA solicitation document. But no further details about Glide Breaker have been released. https://aviationweek.com/defense/rfp-reveals-main-thrust-us-counter-hypersonic-plan
