Supersonic Missile-Assisted Release of Torpedo (SMART) System

  • 02 May 2024

Why is it in the News?

The Defence Research and Development Organisation (DRDO) recently tested a next-generation torpedo release system aimed at boosting the Navy’s anti-submarine warfare capabilities.

What is a SMART System?

  • The SMART system, designed to bolster the Indian Navy's anti-submarine warfare capabilities, represents a fusion of cutting-edge technology and indigenous innovation.
  • With its supersonic capabilities and torpedo release mechanism, the SMART system offers a formidable deterrent against potential submarine threats, enhancing the Indian Navy's operational readiness and maritime defence posture.
  • The SMART system comprises a mechanism by which the torpedo is launched from a supersonic missile system with modifications that would take the torpedo to a far longer range than its own.
    • For example, a torpedo with a range of a few kilometres can be sent a distance to the tune of 1000 km by the missile system from where the torpedo is launched.
  • The system also gives flexibility in terms of the missile system’s launch platform.
  • A number of DRDO laboratories including Defence Research and Development Laboratory (DRDL) and Research Centre Imarat (RCI), both in Hyderabad; Aerial Delivery Research and Development Establishment (ADRDE) in Agra; and Naval Science and Technology Laboratory (NSTL) Visakhapatnam have developed the technologies required for SMART.

Key Features of SMART Anti-submarine Missile System:

  • It is a canister-based, long-range anti-submarine missile system.
  • It has been developed by the DRDO for the Indian Navy.
  • The objective behind the project is to develop a quick reaction system that can launch a torpedo from a standoff distance.
  • The missile has a range of 643 km carrying a lightweight torpedo of range 20 km with a 50 kg high explosive warhead.
  • SMART uses a two-way data link connected to airborne or ship-based submarine detection and identification systems.
  • It can be launched from a surface ship or a truck-based coastal battery.
  • The missile is powered by a dual-stage solid-propellant rocket and utilizes electro-mechanical actuators for course correction.
  • The missile utilizes sea skimming to reduce detection range.
  • The first successful test of SMART was done on 5 October 2020 from Abdul Kalam Island.

Significance:

  • This missile-based mechanism to launch lightweight torpedoes can target submarines hundreds of kilometres away — far beyond the conventional range of lightweight torpedoes.
  • It will be particularly employed in the absence of other assets for immediate action when an enemy submarine is detected.

Red Colobus

The Red colobus, a rare group of imperilled monkeys spread across Africa, is the primary indicator of biodiversity decline in the continent’s tropical forests.

What is Red Colobus?

  • Red colobus monkeys (Piliocolobus spp.), a rare and imperilled group of primates endemic to Africa, serve as crucial indicators of the continent's biodiversity.
  • They are part of the broader colobine family, which predominantly consists of leaf-eating species, distinguishing them from the omnivorous cercopithecines.
  • Alongside Africa's red colobus monkeys, the colobine group also encompasses langurs found in South and Southeast Asia.
  • These distinctive primates are distributed across diverse habitats, ranging from the forests of Senegal to the Zanzibar Archipelago.
    • Despite their ecological significance, red colobus monkeys face a dire threat of extinction, with more than half of the known 18 distinct forms listed as Endangered or Critically Endangered on the IUCN Red List.
  • Their survival is imperilled by various factors, primarily driven by human activities.
  • Hunting for both trade and local consumption poses a significant threat, as does the relentless encroachment on their habitats.
    • Habitat loss, degradation, and fragmentation result from activities such as logging, mining, charcoal production, and the conversion of forests into agricultural lands.
    • These threats collectively endanger the existence of red colobus monkeys, highlighting the urgent need for conservation efforts to safeguard their future.

Conservation of Red Colobus Monkeys:

  • The International Union for Conservation of Nature (IUCN) Species Survival Commission Primate Specialist Group and the African Primatological Society have come together to initiate the Red Colobus Conservation Action Plan.
    • This collaborative effort focuses on making red colobus monkeys a priority target in conservation, ultimately contributing to the preservation of Africa's tropical forests and addressing unsustainable hunting practices.
  • To effectively implement the action plan, a Red Colobus Working Group (RCWG) has been established.
    • This group will provide guidance and ensure that the plan's objectives are met. Additionally, a Red Colobus Conservation Network (RCCN) has been created to promote communication, capacity-building, and monitoring of the conservation efforts for red colobus monkeys.
  • Through this joint venture, the IUCN and the African Primatological Society aim to secure the future of red colobus monkeys while safeguarding the ecosystems they inhabit.

The recent addition of Ajrakh from Kutch to the list of GI-tagged fabrics is a proud moment for India's rich textile heritage.

What is Ajrakh?

  • The Ajrakh fabric is a traditional hand-block printing technique that originated in Kutch, Gujarat.
  • It uses natural dyes and intricate patterns to create beautiful textiles, which are then used to make sarees, dupattas, stoles, and other garments.

  • This fabric has been an integral part of the Kutchi culture for centuries and has now gained recognition on a global level with its GI tag.

What is a GI tag?

  • The GI tag is a certification that identifies a product as originating from a specific geographical location and possessing unique qualities due to that region's traditional knowledge and expertise.
  • It not only adds value to the product but also protects it from imitation or misuse.
    • Ajrakh's GI tag was granted by the Geographical Indications Registry after a long process of documentation and verification of its origin and production techniques.

Some other Indian textiles have received similar recognition.

  • Banarasi Silk: The luxurious Banarasi silk sarees from Varanasi have been coveted by women all over the world for their exquisite designs and fine quality.
