## What is the trajectory of a ballistic missile?

All ballistic missiles share a common, fundamental element. They follow a ballistic trajectory that includes three phases: boost phase, midcourse phase, and terminal phase. The boost phase is the portion of a missile’s flight when it is thrusting to gain the velocity needed to reach its target.

## What is the minimum range of an ICBM?

Submarine-launched ICBMs

Type Minimum Range (km) Maximum Range (km)
M51 8,000 10,000
JL-2 7,400 8,000
JL-3 10,000 12,000
K-5 5,000

What is the minimum range of a missile?

SRBMs follow a path, which stays within Earth’s atmosphere, while intercontinental ballistic missiles (ICBMs) are launched on a sub-orbital trajectory. ICBMs have a minimum range of 5,500 km and are primarily designed for delivery of nuclear warheads.

How far can a submarine shoot a missile?

The submarine’s missiles can strike targets up to 4,000 miles away. ABC News’ Martha Raddatz was given an exclusive tour of the inside of a U.S. nuclear submarine, which is one of the most potent deterrents in the U.S. arsenal .

### How do you calculate missile trajectory?

Trajectory formula

x = Vₓ * t. y = h + Vᵧ * t – g * t² / 2.

### How long would it take for a nuclear missile to reach the US from Russia?

New START limits all Russian deployed intercontinental-range nuclear weapons, including every Russian nuclear warhead that is loaded onto an intercontinental-range ballistic missile that can reach the United States in approximately 30 minutes.

Can the US shoot down nukes?

The answer, experts said, is not a very effective one. The US only has a limited ability to destroy an incoming nuclear intercontinental ballistic missile, a study released last month by the American Physical Society concluded.

What is the smallest ballistic missile?

MGM-134 Midgetman – Wikipedia.

#### Which is the No 1 missile in the world?

BrahMos
Maximum speed Mach 3+
Guidance system Mid-course: Inertial navigation system Terminal: Active radar homing, GPS/GLONASS/GAGAN satellite guidance
Accuracy 1 m CEP
Launch platform Ship, submarine, aircraft, and land-based mobile launchers.

#### Can subs launch missiles underwater?

A submarine-launched ballistic missile (SLBM) is a ballistic missile capable of being launched from submarines. Modern variants usually deliver multiple independently targetable reentry vehicles (MIRVs), each of which carries a nuclear warhead and allows a single launched missile to strike several targets.

What is the deadliest submarine in the world?

The U. S. Navy’s Ohio-class guided missile submarine tops a ranking of the 49 most advanced and dangerous submarines in the world.

What is trajectory formula?

Trajectory formula is given by. y = x t a n θ − g x 2 2 v 2 c o s 2 θ

## How long did it take to calculate a ballistic trajectory?

In fact, the Moore School became something of an extension of the Army’s Ballistic Research Laboratory (BRL), replacing human beings with handheld calculators. A trajectory that could take up to 40 hours to calculate using a desktop calculator could be computed in 30 minutes or so on the differential analyzer.

## Where is the safest place to live if there is a nuclear war?

Modelling by The Guardian in 2016 found that “should atomic annihilation be on the cards”, one of the safest places to live would be Antarctica, because the “sub-zero continent” is “miles from anywhere”, or Easter Island in the South Pacific, which is more than 2,000 miles from South America.

Which countries would survive nuclear war?

New research indicates that Australia and New Zealand are the two best places on Earth to survive a nuclear war.

Does U.S. have secret missile defense?

The US has two Aegis missile defense sites in NATO nations, one in Romania and another in Poland that the Pentagon expects to be operational by the end of this year. The US has said they’re designed to protect Europe against a possible ballistic missile attack from Iran and pose no threat to Russia.

### How many Srbms does Russia have?

But since Russia declared 527 deployed strategic launchers in total as of September 2021, a force of 400 ICBMs would mean Russia only deployed 127 SLBMs and bombers, which seems unlikely (US State Department, Bureau of Arms Control, Verification and Compliance 2021a).

### Which country has the best Defence system in the world?

1. America. The United States of America is without a doubt one of the world’s most powerful countries, and its defence system is no exception. With friends such as the United Kingdom and France, the country possesses a formidable military.

Which country has the most advanced ICBM?

ICBMs by country

S No. Name Operator
1 RS-28 Sarmat Russia
2 BZhRK Barguzin Russia
3 R-36M2 Voevoda USSR
4 UR-100N UTTKh USSR

How deep can a sub launch a missile?

Some early models had to surface to launch their missiles, but modern vessels typically launch while submerged at keel depths of usually less than 50 metres (160 ft).

#### What country has the best submarines?

Realistically, this type of weapon has never stopped improving and developing, which is proof that submarines are an indispensable part of the navy.

1. Seawolf-class, US.
2. Virginia-class, US.
3. Astute-class, UK.
4. Yasen-class, Russia.
5. Sierra-class, Russia.

#### Which country has the quietest submarines?

It can also stay submerged for up to three weeks with little exhaust heat—making the Type-212A virtually undetectable. The German Navy has boasted that it is the quietest submarine in operation today.

How do you calculate rocket trajectory?

The procedure for calculating rocket trajectories is, in principle, straightforward. First, express the resultant force upon the rocket as the sum of thrust, gravity, and drag. Divide the resultant force by rocket mass to find the rocket’s acceleration.

How many hours would it take a human to calculate a trajectory?

A skilled person with a desk calculator could compute a 60-second trajectory in about 20 hours.
