What is a re-entry vehicle?

A re-entry vehicle is the part of a spacecraft that is designed to return through Earth’s atmosphere. It is built to survive intense heating during high-velocity flight through the atmosphere and to protect the crew and/or instruments until it brings them safely to Earth.

What are reentry vehicles made of?

Made by General Electric, the blunt nose is copper and the rest of the metal is stainless steel. It is the only operational “heat sink” RV the United States employed and was designed to protect the warhead from the tremendous heat generated during reentry into the Earth’s atmosphere by absorbtion.

What is reentry missile?

The Maneuverable Reentry Vehicle (abbreviated MARV or MaRV) is a type of ballistic missile whose warhead is capable of autonomously tracking ground targets.

How do MIRVs work?

In a MIRV, the main rocket motor (or booster) pushes a “bus” (see illustration) into a free-flight suborbital ballistic flight path. After the boost phase the bus manoeuvres using small on-board rocket motors and a computerised inertial guidance system.

Why was ceramic coating needed for the reentry vehicle?

During the heat of reentry, the material is converted to a ceramic coating that provides thermal and oxidative stability to the repaired area, thus allowing the vehicle to pass safely from space into the upper atmosphere.

What is re-entry speed?

17,500 miles per hour
It is usually moving parallel to the ground, at a speed of about 7 km/sec or 17,500 miles per hour. The reentry can occur at any time of the day.

Who has MIRV technology?

The Soviet Union quickly followed suit and by the end of the 1970s had developed their own MIRV-enabled ICBM and SLBM technology. Today, the United States, the United Kingdom, and France use MIRV technology on SLBMs. China has MIRVed ICBMs, while Russia deploys both MIRVed ICBMs and SLBMs.

What countries have SLBM?

Types

Type Maximum Range (km) Country
UGM-133 Trident II (D5LE) 12,000 United States
R-13 600 Soviet Union/Russia
R-21 1,650 Soviet Union/Russia
R-27 Zyb 3,000 Soviet Union/Russia

How far apart can MIRVs land?

Some MIRVed missiles can hit targets as far as 1,500 kilometers apart. Land-based MIRVed missiles are considered particularly destabilizing. These missiles are a much more tempting target than traditional land-based missiles, because an attacker can take out several of their enemy’s warheads at once.

What is reentry speed?

It is usually moving parallel to the ground, at a speed of about 7 km/sec or 17,500 miles per hour. The reentry can occur at any time of the day.
