A Docker image, as most of us know, is a static representation of the application, as well as its configuration and dependencies. The Docker Toolbox, Docker Desktop and the Windows Subsystem for Linux (WSL) are all designed to expand its reach and make life easier for developers.ĭocker has revolutionised the DevOps pipeline. Now used everywhere, it is the new way of application deployment. The surface-to-air Python 5 and Derby air defence missile system (SPYDER) is a low-level quick-reaction surface-to-air missile system developed by Rafael Armament Development Authority, and the MBT Missile Division and Elta Radar Division of Israel Aircraft Industries.Docker is a Platform as a Service (PaaS) product, using which developers can build, ship and run their applications inside Docker containers. Rafael is the prime contractor and IAI the major subcontractor for the SPYDER programme. SPYDER is capable of engaging aircraft, helicopters, unmanned air vehicles, and precision-guided munitions. It provides air defence for fixed assets and for point and area defence for mobile forces in combat areas. The SPYDER launcher is designed to fire Python 5 and Derby surface-to-air missiles. SPYDER was selected by the Indian Armed Forces in June 2006. The procurement was finally approved by the approved by the Indian Defence Acquisitions Council in July 2008. A contract worth $1bn for 18 SPYDER systems was awarded to Rafael in September 2008. The SPYDER air defence system was inducted into the Indian Air Force (IAF) in 2017. The Czech Ministry of Defence selected the SPYDER system in September 2020 and started the negotiations for the procurement of four batteries of the SPYDER air defence system. An inter-governmental agreement was signed between the two countries for the supply of four batteries in October 2021. The missile systems will be manufactured as per the specifications of the Czech Army and in partnership with Czech companies RETIA and Vojenský technický ústav. SPYDER-SR short-range surface-to-air missile launcher The deliveries under the contract worth CZK13.69bn ($617m) are expected to be completed by 2026. The SPYDER-SR (short-range) system has 360° engagement capability and the missiles can be launched from the full-readiness state in less than five seconds from target confirmation. The kill range is from less than 1km to more than 15km and at altitudes from a minimum of 20m to a maximum of 9,000m. The system is capable of multi-target simultaneous engagement and also single, multiple and ripple firing, by day and night and in all weathers. ![]() The SPYDER-SR (short-range) system was displayed for the first time at the Paris Air Show 2005 in Le Bourget. SPYDER-MR medium-range surface-to-air missile launcher Rafael developed a medium-range version, SPYDER-MR, which has a range over 35km at altitudes from 20m to 16km. SPYDER-MR carries eight missiles while SPYDER-SR has four. SPYDER-MR also has a new IAI/Elta MF-STAR surveillance radar. The main components of the SPYDER system are the truck-mounted command and control unit, the missile firing unit with Python 5 and Derby missiles, a field service vehicle and missile supply vehicle. The vehicles are air-conditioned and also provide protection against biological and chemical warfare (BCW). Python 5 and Derby missile launcher modes of operation The system is based on a modular design and system maintenance in the field is through very quick module replacement. The system can launch missiles in two modes of operation: lock on before launch (LOBL) and lock on after launch (LOAL). The slant launching method, unlike vertical launch, allows LOBL so the missile’s on-board seeker is locked on to the target before launch. The LOBL mode allows the Squadron Commander to confirm the missile is locked on to the designated target prior to launch, gives high kill probability against short-range high-manoeuvring targets and enables the engagement of designated targets by add-on optical sensors. ![]()
