Defense officials of Ukraine and Sweden met earlier this week to discuss the provisions of aid, equipment maintenance, and cooperation in joint development projects. Particularly notable is the announcement of an initiative to create a new long-range weapon.
While the prospect of such cooperation sounds promising, as it could give Ukrainian Armed Forces a means of deep strikes into russian territory without any imposed range restrictions and a battle-tested weapon to the Swedish military, there's an issue: both parties barely have any experience in carrying out such projects.

For starters, let's consider the Swedish portfolio. Local defense industry giant Saab is set to participate in Germany's program to modernize its Taurus air-launched cruise missile; there's also Stockholm's commitment to join the European Long-Range Strike Approach (ELSA) effort aiming to create a ground-launched attack missile with a range of 1,000 to 2,000 km.
Besides these collaborations, however, Sweden doesn't have any long-range air- or ground-based missiles of its own at the moment.
Based of the information provided by The Military Balance assessment by IISS, Sweden only has RBS-15F anti-ship missiles with an approx. 70 km launch range and AGM-65 Maverick air-to-ground precision-guided missiles with a range of 30 kilometers; its Swedish localization is named RB-75.

The land forces of Sweden have neither "classic" tactical ballistic missiles nor even multiple launch rocket systems. Fire support for ground forces on the battlefield is being entrusted to a fleet of 26 wheeled Archer self-propelled guns, 40 CV90 Mjolner self-propelled mortars (local name: Gkpbv 90), 108 towed M/86 mortars (81mm) and 80 towed M/41D mortars (120mm).
Fair to note that Sweden also has its domestically developed RBS 15 coastal defense missile system, a fairly powerful weapon, with an impressive range of 300 kilometers in the latest Mk4 version. The issue is the number of these systems produced. The Military Balance counts only one battery as of early 2024.

Sort of a counterpart to the RBS 15 is Ukraine's Neptune, also a surface-launched anti-ship missile which was modified after the outbreak of the all-out war with russia to be able to strike targets on the ground.
There are also announced Ukrainian projects of Palianytsia and Peklo "missile drones," reportedly already used in strikes on russia, as well as an undisclosed tactical ballistic missile, largely assumed to refer to the unfinished Sapsan (otherwise known as Hrim-2) SRBM system.
That said, Ukraine has yet to successfully deploy a long-range missile of its own. Thus, the cooperation with Sweden is a chance for both countries to exchange technologies and gain more experience in missile programs to ultimately field a product proven in real combat that may garner interest from potential export customers.
