Qassem Bassir
The Qassem Bassir (also transliterated Qasem or Ghasem Bassir) missile is an Iranian medium-range ballistic missile (MRBM) unveiled in May 2025. With a solid-fueled, two-stage system, it is presented as an improved variant of Iran’s Haj Qassem series, named after Quds Force commander Qassem Soleimani. Iranian officials state the Qassem Bassir has a range of about 1,200 km, and features enhanced guidance and countermeasure resistance. The missile was revealed by Iranian Defense Minister Brig. Gen. Aziz Nasirzadeh on Iranian state television on 4 May 2025. Iran claims the Qassem Bassir missile can penetrate advanced missile defenses, and can strike selected targets (e.g. runways, aircraft hangars) with "pinpoint" accuracy without GPS, though western analysts have cast doubt on these claims which are likely tinted with internal propaganda. Despite ongoing nuclear-deal talks with Washington, Iran chose to showcase its new missile, warning that it would strike back at the Unite ...

Carbon-fiber
Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers (Commonwealth English), carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic (CFRP, CRP, CFRTP), also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications. The binding polymer is often a thermoset resin such as epoxy, but other thermoset or thermoplastic polymers, such as polyester, vinyl ester, or nylon, are sometimes used. The properties of the final CFRP product can be affected by the type of additives introduced to the binding matrix (resin). The most common additive is silica, but other addi ...

Ministry Of Defence And Armed Forces Logistics (Iran)
The Ministry of Defence and Armed Forces Logistics (MODAFL; ) is the defence ministry of Iran and part of the country's executive branch. It thus reports to the President of Iran, not to the Commander-in-Chief of the Iranian Armed Forces. Unlike many countries, the ministry is not involved with in-the-field military operational command of the armed forces. Instead it is responsible for planning, logistics and funding of the Armed Forces of the Islamic Republic of Iran while the General Staff of the Armed Forces of the Islamic Republic of Iran, a separate institution under command of the supreme leader of Iran, has control over the forces. The MODAFL is also the major player in the defence industry of Iran, with multiple conglomerates and subordinates active in research and development, maintenance and manufacturing of military equipment. It annually exports military equipment manufactured in Iran to forces of countries such as Syria, Iraq, Venezuela, and Sudan (the latter ce ...

Electro-optical Sensor
Electro-optical sensors are electronic detectors that convert light, or a change in light, into an electronic signal. These sensors are able to detect electromagnetic radiation from the infrared down to the ultraviolet wavelengths. They are used in many industrial and consumer applications, for example: * Lamps that turn on automatically in response to darkness * Position sensors that activate when an object interrupts a light beam * Flash detection, to synchronize one photographic flash to another * Photoelectric sensors that detect the distance, absence, or presence of an object Function An optical sensor converts light rays into electronic signals. It measures the physical quantity of light and then translates it into a form readable by an instrument. An optical sensor is generally part of a larger system that integrates a source of light, a measuring device, and the optical sensor. This is often connected to an electrical trigger. The trigger reacts to a change in the si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inertial Navigation System
An inertial navigation system (INS; also inertial guidance system, inertial instrument) is a navigation device that uses motion sensors (accelerometers), rotation sensors (gyroscopes) and a computer to continuously calculate by dead reckoning the position, the orientation, and the velocity (direction and speed of movement) of a moving object without the need for external references. Often the inertial sensors are supplemented by a barometric altimeter and sometimes by magnetic sensors (magnetometers) and/or speed measuring devices. INSs are used on mobile robots and on vehicles such as ships, aircraft, submarines, guided missiles, and spacecraft. Older INS systems generally used an inertial platform as their mounting point to the vehicle and the terms are sometimes considered synonymous. Design Inertial navigation is a self-contained navigation technique in which measurements provided by accelerometers and gyroscopes are used to track the position and orientation of an object ...

Zolfaghar (missile)
The Zolfaghar () missile is an Iranian road-mobile, single-stage, solid-propelled SRBM named after Zulfiqar the sword of Ali ibn Abi Talib. It is believed to be derived from the Fateh-110 SRBM family (possibly the Fateh-313 missile). The Aerospace Industries Organization unveiled the weapon in 2016. It entered service in 2017. It was first used in the 2017 Deir ez-Zor missile strike and was therefore one of the first used mid-range missiles since 30 years. Design According to Iranian sources, the Zolfaghar missile has a length of , a diameter of , and a launch weight of with a warhead. The warhead is designed to separate in the missile's midcourse phase, making it more difficult to detect, track, and intercept than unibody missiles like the 9K720 Iskander. According to Iranian media sources, a naval variant called the "Zolfaqar Basir" has also been developed, which the IRGC claims has a range of more than .

Contrast Seeker
Optical contrast seekers, or simply contrast seekers, are a type of missile guidance system using a television camera as its primary input. The camera is initially pointed at a target and then locked on, allowing the missile to fly to its target by keeping the image stable within the camera's field of view. The first production missile to use a contrast seeker was the AGM-65 Maverick, which began development in the 1960s and entered service in 1972. The system has not been widely used, as other guidance technologies like laser guidance and GPS have become more common, but the same basic concept is used in cameras to track objects, including the systems used to aim the laser designators. Contrast seekers should be distinguished from television guidance systems, in which a live television signal is broadcast to the launch platform, which then uses manual direction to attack the target. Examples of TV guidance include the Martel and AGM-62 Walleye. The term "contrast contour" i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ballistic Missile Flight Phases
A ballistic missile goes through several distinct phases of flight that are common to almost all such designs. They are, in order: * boost phase when the main boost rocket or upper stages are firing; * post-boost phase when any last-minute changes to the trajectory are made by the upper stage or warhead bus and the warheads, and any decoys are released; * midcourse which represents most of the flight when the objects coast; and * terminal phase as the warhead approaches its target and, for longer-ranged missiles, begins to reenter the atmosphere. These phases are particularly important when discussing ballistic missile defense concepts. Each phase has a different level of difficulty in performing an interception, as well as a different outcome in terms of its effect on the attack as a whole. For instance, defenses that take place during the terminal phase are often the simplest to build in technical terms as they require only short-range missiles and radars. However, terminal def ...

Hypersonic Flight
Hypersonic flight is flight through the atmosphere below altitudes of about at Hypersonic speed, speeds greater than Mach 5, a speed where Dissociation (chemistry), dissociation of air begins to become significant and high heat loads exist. Speeds over Mach 25 have been achieved below the thermosphere as of 2020. Hypersonic vehicles are able to maneuver through the atmosphere in a #Weapons, non-parabolic trajectory, but their aerodynamic heat loads need to be managed. History The first manufactured object to achieve hypersonic flight was the two-stage RTV-G-4 Bumper, Bumper rocket, consisting of a WAC Corporal second stage set on top of a V-2 rocket, V-2 first stage. In February 1949, at White Sands V-2 Launching Site, White Sands, the rocket reached a speed of , or about Mach 6.7. The vehicle, however, burned on atmospheric re-entry, and only charred remnants were found. In April 1961, Russian Major Yuri Gagarin became the first human to travel at hypersonic speed, dur ...

Transporter Erector Launcher
A transporter erector launcher (TEL) is a missile vehicle with an integrated tractor unit that can transport, elevate to a firing position and launch one or more rockets or missiles. History Such vehicles exist for both surface-to-air missiles and surface-to-surface missiles. Early on, such missiles were launched from fixed sites and had to be loaded onto trucks for transport, making them more vulnerable to attack, since once they were spotted by the enemy they could not easily be relocated, and if they were it often took hours or even days to prepare them for launch once they reached their new site. Usually a number of TELs and TELARs are linked to one command post vehicle (CP or CPV). They may use target information from target acquisition, designation and guidance radar (TADAGR or TAR). Transporter erector launcher and radar (TELAR) A transporter erector launcher and radar (TELAR) is a type of TEL that also incorporates part or all of the radar system necessary for firi ...

Flight Control Surfaces
Flight control surfaces are aerodynamic devices allowing a pilot to adjust and control the aircraft's flight attitude. The primary function of these is to control the aircraft's movement along the three axes of rotation. Flight control surfaces are generally operated by dedicated aircraft flight control systems. Development of an effective set of flight control surfaces was a critical advance in the history of development of aircraft. Early efforts at fixed-wing aircraft design succeeded in generating sufficient lift to get the aircraft off the ground, however with limited control. The development of effective flight controls allowed stable flight. A conventional fixed-wing aircraft uses three primary flight control surfaces– aileron, rudder and elevator to control the roll, yaw, and pitch respectively. Secondary flight control surfaces might include spoiler, flaps, and slats on the wings. The main control surfaces of a fixed-wing aircraft are attached to the airfram ...

Thrust Vectoring
Thrust vectoring, also known as thrust vector control (TVC), is the ability of an aircraft, rocket or other vehicle to manipulate the direction of the thrust from its engine(s) or motor(s) to Aircraft flight control system, control the Spacecraft attitude control, attitude or angular velocity of the vehicle. In rocketry and ballistic missiles that fly outside the atmosphere, aerodynamic Flight control surfaces, control surfaces are ineffective, so thrust vectoring is the primary means of Flight dynamics (fixed-wing aircraft), attitude control. Exhaust vanes and Gimbaled thrust, gimbaled engines were used in the 1930s by Robert H. Goddard, Robert Goddard. For aircraft, the method was originally envisaged to provide upward vertical thrust as a means to give aircraft vertical (VTOL) or short (STOL) takeoff and landing ability. Subsequently, it was realized that using vectored thrust in combat situations enabled aircraft to perform various maneuvers not available to conventional-en ...
