In February 2020, Raytheon completed the first radar antenna array for the US Army's new missile defense radar, known as the Lower Tier Air and Missile Defense Sensor (LTAMDS), to replace the service's Patriot air and missile defense system sensor. In April 2020, the company merged with United Technologies Corporation to form Raytheon Technologies . The merged company

180-477: A contract to build 3DELRR, a next-generation long-range radar system, for the USAF worth an estimated $ 1 billion. The contract award was immediately protested by Raytheon's competitors, Lockheed Martin and Northrop Grumman. After re-evaluating the bids following the protests, the USAF decided to delay awarding the 3DELRR EMD contract until 2017 and was to issue an amended solicitation at the end of July 2016. In 2017

240-513: A contract to build the devices. Within a few month, Raytheon began to manufacture magnetron tubes for use in radar sets, and then complete radar systems . During the war, Raytheon also pioneered the production of shipboard radar systems, particularly for submarine detection. Raytheon was also a contractor for the mass-production of miniature shock-resistant vacuum tubes used in proximity fuses . These tubes were difficult to manufacture and required rigorous attention to detail. At war's end in 1945,

300-687: A follow-on, the RAYCOM, which was never completed. In 1954, it entered into a joint venture with Honeywell to form the Datamatic corporation. However it sold its interest to Honeywell a year later, before introduction of the DATAmatic 1000 system. In 1958, Raytheon acquired the marine electronics company Applied Electronics Company to make commercial marine navigation and radio gear, as well as less-expensive Japanese suppliers of products such as marine/weather band radios and direction-finding gear .

720-470: Is also a much older cluster and physical models still lead to a distance of 450-600pc. Zeta Puppis shows a high space velocity and very high rotation rate, and it has been speculated that it is a runaway star resulting from a supernova in a binary system, possibly the progenitor of the Gum Nebula . Models of binary systems are able to reproduce the properties of Zeta Puppis following mass transfer from

780-630: Is also heavily involved in the satellite sensor business. Much of its Space and Airborne Systems division in El Segundo , CA is devoted to this, a business it inherited from Hughes . Examples of programs include: As part of the company's growing homeland security business and strategic focus, Raytheon has teamed with other contractors to develop an Advance Spectroscopic Portal (ASP) to allow border officials to view and identify radioactive materials in vehicles and shipping containers more effectively. Raytheon also manufactures semiconductors for

840-449: Is also used as a method to establish its distance. The physical properties of the star depend strongly on its distance, with its bolometric luminosity being 813,000  L ☉ at 460 pc and only about 450,000  L ☉ at 332 pc . Its rotational velocity and period constrain the possible distances and inclination of the star. The rotational period was long considered to be just over five days, being

The ALE-50 system consists of a launcher and launch controller installed on the aircraft (usually on a wing pylon), and one or more expendable towed decoys . Each decoy is delivered in a sealed canister and has a ten-year shelf life . When deployed, the decoy is towed behind the host aircraft, protecting

1200-458: Is much older than Zeta Puppis and the space velocity does not lead back to that cluster. Many physical models and the original Hipparcos parallax measurements did lead to a distance value of around 450pc, but the revised Hipparcos reduction gave a much lower distance near 333pc. A recent dynamical study points to Zeta Puppis originating in the Trumpler 10 OB association at around 300pc, but this

1260-573: Is no longer taking on new orders, having been on the premises for 57 years. In the framework of Ground-Based Midcourse Defense , Raytheon is developing a Ground Based Interceptor (GBI) that includes a booster missile and a kinetic Exoatmospheric Kill Vehicle (EKV), along with several key radar components, such as the Sea-Based X-Band Radar (SBX) and the Upgraded Early Warning Radar (UEWR).

1320-532: Is one of the hottest, and most luminous, stars visible to the naked eye. It is one of the sky's few naked-eye class O-type stars as well as one of the closest to Earth . It is a blue supergiant , one of the most luminous stars in the Milky Way . Visually it is over 10,000 times brighter than the Sun , but its high temperature means that most of its radiation is in the ultraviolet and its bolometric luminosity

1380-478: Is over 500,000 times that of the Sun. It is also the 72nd brightest star in terms of apparent magnitude from Earth. It is a runaway star , meaning it has an unusually large space velocity , probably caused by being ejected from a close binary system when its companion exploded as a supernova. Zeta Puppis is typical of O-type stars in having an extremely strong stellar wind , measured at 2,500 km/s, which sees

1440-430: Is ranked as a supergiant. The brightness of Zeta Puppis varies slightly but regularly. Its apparent magnitude varies between a peak of 2.24 and a minimum of 2.26 over 1.78 days. The variations had been thought to be the due to the pulsations of an α Cygni variable , but are too predictable and regular. The eclipse-like light curve is now thought to be due to rotation of the star which has large irregular features at

1500-660: The Arms Export Control Act and the International Traffic in Arms Regulations , or ITAR. The company was allowed to pay only half the fine to the government and to put half of the fine toward “remedial compliance measures to strengthen RTX’s compliance program.” In October 2024, RTX agreed to pay nearly $ 1 billion to settle allegations of defrauding the U.S. Defense Department and bribing a Qatari military official. Company officials said

1800-586: The Rydberg formula if half-integers were used instead of whole integers. It was later found that these were due to ionized helium . Early suggestions for the birthplace of Zeta Puppis were the very young Vela R2 stellar association at around 800pc and the Vela OB2 association at 450pc. Neither origin is satisfactory. A distance of 800pc requires an abnormally high luminosity, while the Vela OB2 association

1860-676: The United Kingdom invented the magnetron , a specialized microwave -generating electron tube that markedly improved the capability of radar to detect enemy aircraft. American companies were then sought by the US government to perfect and mass-produce the magnetron for ground-based, airborne, and shipborne radar systems, and, with support from the Massachusetts Institute of Technology 's Radiation Laboratory (recently formed to investigate microwave radar ), Raytheon received

3120-469: The name Naos for this star on 21 August 2016 and it is now so entered in the IAU Catalog of Star Names. USS Naos (AK-105) was a United States Navy Crater class cargo ship named after the star. Zeta Puppis has been extensively studied because of the rarity of such hot massive stars and its relative closeness to Earth, but its physical parameters and distance are still poorly known. It would be

3180-652: The period of certain variations observed in its spectrum. However, it is now thought that less obvious brightness variations with a period of 1.78 days are caused by bright areas on the surface of the star as it rotates. With the projected equatorial rotational velocity of 219 km/s , this means that the star is rotating at close to its break-up velocity and that the equator must be inclined less than about 33° to us. The angular size of Zeta Puppis has been measured interferometrically to be 0.41 mas, and photometrically to be 0.38 mas. In 1896, Williamina Fleming observed mysterious spectral lines from Zeta Puppis, which fit
