The roles set out for these vessels are maritime surveillance, search and rescue, protection of offshore assets such as installations at sea, humanitarian assistance and disaster relief, and anti-piracy missions.

The Ministry of Defence explained that ships of this class take their names from India's rich heritage, and that Srishti means creation, or the act of creating, in Sanskrit.

Yard 1283, named Srishti, was launched there on 27 October 2026 in the presence of the Secretary (Defence Finance) and senior officers of the Indian Navy and the Ministry of Defence.

The Republic of Singapore Navy sent RSS Supreme, a Formidable-class stealth frigate, and the ship carried an embarked SH-70B helicopter during the exercise.

SIMBEX-2026 was run in two stages. The harbour stage was held in port at Visakhapatnam and covered subject matter expert exchanges, cross-deck visits, planning conferences and sporting events.

SIMBEX is short for Singapore-India Maritime Bilateral Exercise, and it is conducted between the Indian Navy and the Republic of Singapore Navy.

This is India's stated maritime vision, and the Colombo port call by the First Training Squadron is placed within it because the visit turns on joint training, professional exchange and shared maritime security rather than one-sided help.

A Passage Exercise is the short exercise two navies run when their ships are in company, usually as one of them sails on after a harbour visit, and it lets crews practise manoeuvring, communication and formation keeping together.

These three vessels sailed as the First Training Squadron on this deployment and entered Colombo harbour, where the Sri Lanka Navy welcomed them with a ceremonial reception and a naval band.

This statement is false, because sound in air travels as longitudinal waves, not transverse waves. In a longitudinal wave, the particles of the medium vibrate back and forth along the direction in which the wave moves, forming compressions and rarefactions.

Power is the reciprocal of the focal length in metres, so P = 1 ÷ 0.25 m = +4 D. The power of a lens tells how strongly it converges or diverges light.

A solar cell turns the energy of sunlight directly into electricity through the photovoltaic effect. A solar cell is a large p-n junction, usually made of silicon.

With the same voltage, heat varies inversely as resistance, and the parallel resistance is one-fourth of the series resistance. The two wires are identical, so each has the same resistance R. In series the total resistance is R + R = 2R; in parallel it is R/2.

Tidal volume is the volume of air breathed in or out in one normal, quiet breath, about 500 mL in a healthy adult.

The cornea is a clear layer made of cells and proteins, chiefly collagen fibres laid out in a regular pattern that keeps it transparent.

The time period of a simple pendulum depends on its length but not on the mass of the bob, so halving the length divides the period by √2.

Potential difference is the work done per unit charge, so V = W/Q = 24 J ÷ 2 C = 12 V. The potential difference between two points is the work needed to move one coulomb of charge from one point to the other.

Pepsin works in the strongly acidic stomach, while trypsin works in the mildly alkaline small intestine. Pepsin is secreted by the chief cells of the stomach as inactive pepsinogen, which hydrochloric acid from the parietal cells turns into pepsin.

"Not Me But You" is the motto of the NSS, and it stands for selfless service to others. The National Service Scheme was launched on 24 September 1969, the birth centenary year of Mahatma Gandhi, with the aim of building the personality of students through community service.
