Iran Conducts Naval Drill Sustainable Power 1404 – First Since War With Israel

Iran also conducted its first large-scale naval maneuver since the war with Israel in June 2025, called Sustainable Power 1404. The two days exercise was conducted in the Gulf of Oman and the northern part of the Indian Ocean, which involved the launches of the missiles at the targets located at the sea. The drill was carried out to enhance battle preparedness, reaffirm command cooperation and present deterrence following a series of confrontations. IRIS Ganaveh and vessel IRIS Sabalan fired Nasir and Qadir cruise missiles with precision strike capability. The drill is indicative of the willingness of Iran to reestablish its war image and tanks on the waters of the region.

Context

  • The exercise is the culmination of the 12-day war in June 2025 in which Israel had launched an attack against Iranian air defences and nuclear facilities, prompting Iranian responses using its missiles.

  • It is coming at a time of regional tensions and Israeli military practice of Iranian nuclear site raids.

  • Iran wants to demonstrate that it is resolute, threatening, and powerful in vital maritime routes.

Conclusion 

Sustainable Power 1404 is the reflection of the will of Iran to overcome the conflict and assert the naval presence in the region as soon as possible. The drill embodies both military preparedness and threat of strategic deterrence as the tension of Israel is on the rise. Its magnitude and the extent demonstrates the intentions of Tehran to be an outspoken maritime power in West Asia.

NASA Launches AI Model Surya to Predict Space Weather

NASA, along with IBM, has released an AI model called Surya, which aims at enhancing space weather forecasting. Trained on about a decade of data from the Solar Dynamics Observatory, it is able to anticipate solar flares and eruptions as far as two hours in advance. Surya introduces the spectral block layers and transformer architecture to find faint patterns of solar activities with 16 percent more accuracy than the models used before. It has been tested on 2015 St. Patrick Day geomagnetic storm, in which it accurately simulated the event. It has been published as open-source so that worldwide cooperation is possible in order to enhance prevention of solar threats.

Context 

  • Solar flares and CMEs pose a danger to satellites, power grids, aviation and the safety of astronauts.

  • Established forecasting techniques are sometimes not capable of early and accurate prediction of such events.

  • NASA wants to use AI-enabled heliophysics to prepare and resilience globally.

Key Points

Why It Matters

  • Solar activity may be involved.

  • Damage satellites

  • That is the reason why power outages on a large scale happen.

  • Interfere with an aircraft and GPS signals

  • Put astronauts in peril in space

  • Improved forecasting leads to improved global readiness

Surya’s Features

  • Its backbone consists of: Spectral block layers and transformer model

  • Forecasts: Solar flares, the velocity of solar wind, the extreme profiles of ultraviolet

  • Accuracy: 16 % increase over conventional models

  • Verified: 2015 St. Patrick geomagnetic storm successfully reproduced

Global Collaboration

  • Partners: NASA, IBM, NSF, NVIDIA, universities and research institutes

  • Open-source publication: promotes global study & optimisation

  • Develops the basis of heliophysics on AI assistance

Strategic Significance

  • Advance warnings: miniaturizing of satellite contingencies and power grid interruption

  • Supports safety in aviation and space missions

  • Accelerates the work of AI + space science in modern technologically-advanced societies

Conclusion 

NASA AI model Surya is a first in predictive space weather forecasting. It has an open-source structure that supports global collaboration to protect satellites, astronauts and key infrastructure. In a world where space weather is an increasingly dangerous reality, Surya is ensuring greater preparedness across the world in facing its hazards, and in building a future where the world is connected safely.
