Four records cover the heaviest rockets in this domain. YERINA 2 is an unguided 262 mm rocket of 338.1 kg quoted beyond 60 km with a 115 kg warhead and fuze, and the RM-262 solid propellant motor that carries the same range and warhead figures is listed separately. A second 262 mm record describes an unguided rocket for modular launchers reaching 70 km with a CEP of about 400 m and a choice of warhead. YERINA 1 is the correctable 400 mm rocket, quoted to 285 km.
Unguided 262 mm artillery rocket for engaging area targets, offering advantages over guided tactical missiles in being cheaper, simpler to operate, quicker in response time and immune to jamming in flight, with a maximum range beyond 60 km.
Solid propellant rocket motor of 262 mm calibre with a single-piece cylindrical propellant grain inhibited along the outer surface and forward end, containing two propellants of differing burning rate to give a high loading factor and almost neutral burning.
An unguided 262 mm artillery rocket for modular multiple launch rocket systems, reaching 70 km with a CEP of about 400 m, offered either with a high explosive fragmentation warhead containing steel balls or with a thermobaric warhead, in both cases fitted with an impact or proximity fuze.
Correctable 400 mm artillery rocket designed to destroy enemy area targets and large point targets such as military bases, airports, ports and port facilities, transport nodes and factories at distances of up to 285 km.

How long-range rockets are specified in tender documents
Every record gives the calibre, an overall length and a total mass. Warhead mass appears on all four: with fuze on YERINA 2 and RM-262 at 115 kg, as a warhead weight of 140 kg on the 70 km rocket and 200 kg on YERINA 1. Maximum range is stated throughout; maximum velocity of 1130 m/s only on YERINA 2 and RM-262. YERINA 2 gives a fin span of 566 mm, and YERINA 1 the span of its foldable fins at 854 mm and of its canards at 720 mm together with the length of its container-type launcher. YERINA 2 adds apogee and time of flight, and the 70 km record adds circular error probable and fuze options. Propellant type is named on three records.
The YERINA name and the RM-262 motor
YERINA covers two very different items: YERINA 2 at 262 mm and 338.1 kg, and YERINA 1 at 400 mm, about 1500 kg at launch and 8250 mm long. RM-262 is a motor rather than a complete rocket, quoted at 213 kg total with 145.6 kg of propellant and a burning time of 6.2 s. The fourth record is an unnamed 262 mm rocket of 400 kg.
Questions about this equipment
Are these four records all unguided rockets?
No. Two of the four describe unguided artillery rockets: YERINA 2 and the 262 mm rocket quoted to 70 km. YERINA 1 is described instead as correctable, with a stated circular error probable under 50 m, foldable fins of 854 mm span and canard control surfaces of 720 mm, launched from a container-type launcher of 8600 mm. The fourth record, RM-262, is a rocket motor rather than a complete rocket.
Why is a rocket motor listed on its own?
RM-262 is offered as a separate item. Its record describes a single-piece cylindrical propellant grain inhibited along the outer surface and forward end, holding two propellants of differing burning rate, and quotes a total impulse of 329220 Ns for a burning time of 6.2 s.
