With reference to BrahMos missile, consider the following statements : 1. It has a flight range of up to 290 km. 2. It is capable of attaining a speed of 2.8 Mach. 3. Its cruising altitude could be up to 30 km. Which of the statements given above is/are correct?
1 and 2
Understanding BrahMos Missile Capabilities
Let's analyze the statements about the BrahMos missile to determine which ones are accurate regarding its capabilities and specifications.
We will examine each statement individually based on known information about the BrahMos missile system.
Statement 1: It has a flight range of up to 290 km.
The original BrahMos missile was developed with a range of 290 km. This range was initially limited due to the Missile Technology Control Regime (MTCR), which restricts the export of missiles with a range exceeding 300 km and a payload greater than 500 kg by its member states. As India is now a member of the MTCR, the range of newer versions of BrahMos has been extended significantly beyond 290 km. However, the baseline or initial specification often refers to the 290 km range. Therefore, stating it has a range of "up to 290 km" is correct, especially referring to the initial variants.
Analysis of Statement 1: This statement is considered correct, referencing the original design parameters of the BrahMos missile.
Statement 2: It is capable of attaining a speed of 2.8 Mach.
BrahMos is renowned for being one of the fastest supersonic cruise missiles in the world. Its speed is typically stated as Mach 2.8, which means it travels 2.8 times the speed of sound. Some reports even suggest that advanced versions can reach speeds closer to Mach 3. This high speed makes it difficult for most existing missile defense systems to intercept.
Analysis of Statement 2: This statement is correct, accurately reflecting the typical operational speed of the BrahMos missile.
Statement 3: Its cruising altitude could be up to 30 km.
Cruise missiles like the BrahMos are designed to fly relatively low to avoid radar detection. While the BrahMos can fly at various altitudes depending on the mission profile, including high altitudes for reduced drag and increased range during the cruise phase, a cruising altitude of up to 30 km (approximately 100,000 feet) is exceptionally high for a typical cruise missile profile. Supersonic cruise missiles often fly at altitudes between 10 km and 15 km during their cruise phase, dropping to very low altitudes (like 10 meters) during the terminal attack phase. An altitude of 30 km is more characteristic of high-altitude aircraft or stratospheric balloons, not a standard cruising altitude for a cruise missile like BrahMos.
Analysis of Statement 3: This statement is incorrect. A cruising altitude of up to 30 km is not typical for the BrahMos missile.
Conclusion on BrahMos Statements
Based on the analysis of each statement:
- Statement 1 is correct (referencing the initial/standard range).
- Statement 2 is correct (speed is typically Mach 2.8).
- Statement 3 is incorrect (cruising altitude is not typically up to 30 km).
Therefore, the statements that are correct are 1 and 2.
| Statement No. | Statement Description | Accuracy | Reasoning |
|---|---|---|---|
| 1 | Flight range up to 290 km | Correct | Matches initial design limit (MTCR). |
| 2 | Speed of 2.8 Mach | Correct | Typical supersonic speed of BrahMos. |
| 3 | Cruising altitude up to 30 km | Incorrect | Cruising altitude is much lower for tactical reasons. |
Revision Table: Key BrahMos Missile Features
| Feature | Specification/Detail |
|---|---|
| Type | Supersonic cruise missile |
| Speed | Mach \(\text{2.8}\) (approx. \(\text{3450 km/h}\) or \(\text{2145 mph}\)) |
| Range (Initial) | \(\text{290 km}\) |
| Range (Extended) | \(\text{400 km}\), \(\text{500 km}\), and potentially higher for newer variants |
| Altitude Profile | Can fly at various altitudes, including low-level (down to \(\text{10 m}\)) and higher cruise altitudes (typically up to \(\text{15 km}\)). \(\text{30 km}\) is not a standard cruising altitude. |
| Launch Platforms | Land, sea (ships), air (aircraft) |
Additional Information on BrahMos Missile
The BrahMos missile is a joint venture between India (Defence Research and Development Organisation - DRDO) and Russia (NPO Mashinostroyeniya). The name BrahMos is a portmanteau formed from the names of two rivers: the Brahmaputra of India and the Moskva of Russia. It is considered a highly versatile missile system due to its ability to be launched from multiple platforms and its effectiveness against both land and sea targets. The development of extended-range versions and further advancements like hypersonic variants are ongoing.
Understanding the specifications like range, speed, and operational altitude is crucial for competitive exams focusing on defense technology and current affairs. The BrahMos represents a significant capability in India's defense arsenal.
